=** The Respiratory System **=



//Oxygen is needed for most life to exist. Without oxygen, the cells in the body would not be able to release the energy in food for power, and they would die within minutes.//

//The parts of the body responsible for supplying oxygen the nose, nasal passages, windpipe, lungs, and breathing muscles make up what is called the respiratory system. In the nose and nasal passages, incoming air is warmed, moistened, and cleaned of foreign particles. Then the air travels down through the windpipe, or trachea, which divides into two branches called bronchial tubes, one entering each lung. The bronchi branch again and again inside the lungs, similar to the branching pattern of a tree, finally becoming hair-like tubes called terminal bronchioles. At the end of the terminal bronchioles are microscopic bubble-like structures called alveoli. Each lung contains 300 million alveoli. If the surface of all the alveoli were spread out flat it would cover a tennis court.//

===The respiratory system helps us breathe in and out, so oxygen can be pumped through our body and carbon dioxide can be removed from our body. The term “respiration” is quite often used, and it is the process by which living things produce energy form food. Adenosine triphosphate, often known as “ATP”, is a chemical that allows for cellular respiration. During cellular respiration, energy is released. The word “respiration” equals to food plus oxygen, which equals to energy plus carbon dioxide plus water. This respiratory system is mainly made up of many organs. When we breathe in oxygen, the blood that gets pumped out of the heart sends the oxygen to the rest of our body. That way we can stay alive.=== ===The nose and mouth is where this whole system begins. That’s because this place is where oxygen first enters to our body, and is also where carbon dioxide leaves. When air enters our nose, it gets filtered by tiny hairs that grow in our nose. Air can also come through our mouth, but air is not filtered as much, when it enters in through our mouth. “Sinuses” help out with our respiratory system. They help moisten and heat the air that we breathe in and out.=== ===The pharynx and the trachea is where air passes from your nose, to your bronchi tubes and lungs. Another word for pharynx is “throat”, and for trachea, it is “wind pipe”. The trachea is held open by incomplete rings of cartilage. Without these rings, our trachea might close off and air wouldn’t be able to get to and from our lungs. The trachea splits up into 2 bronchi tubes. One of it is the tube that connects to the lungs, and the other one is where food travels, to make energy. There tubes (bronchi tube and esophagus) keep splitting up, and form bronchial trees. These tubes keep getting smaller and smaller until they finally end with small air sacs called “alveoli”.=== ===Alveoli are tiny air sacs that fill up with air/oxygen when we breathe in. Our alveoli are surrounded by many tiny blood vessels called “capillaries”. Capillaries connect the artery, and the veins. The walls of our alveoli and capillaries are so thin, that oxygen or carbon dioxide can pass through. They travel right into, or out of our blood stream.=== ===This is how the respiratory system works. First, we breathe in oxygen. We get this oxygen from the air around us. When we breathe in, it goes to our lungs. When we breathe out, carbon dioxide goes out of our body. But what if we exercise? Does it effect how we breathe? Yes, it does. That’s because we need more oxygen to make energy, when we exercise. So, to get more oxygen, we have to breathe harder. The oxygen that we breathe in will then go to our lungs. We have 2 lungs; the right lung and the left lung, but the right lung is slightly larger than the left one. It’s because we have to leave some space for the heart to fit in. The lungs are also similar to bagpipes, which is one kind of an instrument in Scotland. When the person blows in to the tube, the bag underneath the tube (connected) will blow up. That makes the instrument make sound. After the oxygen goes to our lungs, it passes through the tiny bronchial tubes, which end up as tiny air sacs, called “alveoli”. When the oxygen reaches the alveoli, they will have a gas exchange. During the gas exchange, the oxygen will replace with the carbon dioxide. Below the place where gas exchange is occurred, there is a part called “diaphragm”. This part controls the air pressure and our breathing system. When the diaphragm contracts, oxygen is pumped to our lungs. When the diaphragm relaxes, carbon dioxide is pumped out of the lungs. When we relax, our diaphragm stays at the normal position but when we get nervous, it goes up, and we breathe more frequently. After the gas exchange, the carbon dioxide will get brought to the lungs, and be removed out of our body.=== ===The respiratory system is an important system in our body. When oxygen comes into our body, we are breathing in. When we breathe in, we usually breathe in from our nose. In our nose, we have substances called “mucus”. They catch unknown matter and try to prevent it from entering our body. By them, moistening our nose, it prevents tissues from drying out. They also send signals, when we catch a cold. When carbon dioxide goes out of our body, we are breathing out. If we don’t have this system in our body, we wouldn’t exist in this world. This system controls respiration, and so we can stay alive.===

The Best System Ever Getting into the human respiratory system with cool facts… Do you know what the respiratory system is? It is one of the systems of our body and it is a very important system in our body. The parts of them are the nasal cavity, nose, mouth, throat, windpipe, diaphragm…and still more! Food plus oxygen is energy! Did you know that we get oxygen from those nutrients in the plants? We also get oxygen from the air around us. Now, let’s go into the very cool system. The system begins with the nose and the mouth. This system starts from the nose and the mouth because we breathe with them. ^^ We breathe in with our nose and out the mouth. As we breathe in, oxygen comes inside our body and as we breathe out, the carbon dioxide will go out of our body. The parts of the nose and mouth are the nasal cavity, nostril, oral cavity, and the pharynx. In our nose, there is hair and there is something that covers them which is called mucus. Its job is to coat the lining of the airway. If we go down our body, there will be throat and the windpipe. As I’ve told you, under nose and mouth, there is the throat, and the windpipe, under. Actually, the windpipe is called the trachea and the throat is also called the pharynx. Trachea is a pipe which let the food and air pass through. Trachea is also one of the important parts of our body. If we go down the windpipe which is trachea, we will see a flap of skin called epiglottis. It helps your digestion. It seperates food and air to different places of our body. The food will be sent to the stomach and air will be sent to the lungs. Under the trachea, there will be our LUNGS! Lungs are the main part of the respiratory system. There are 2 lungs. The 2 parts are the left and right lung. Your lungs will get dirty if you smoke. The reason is because cigarette is not got for our body, and the cigarette is very harmful. Lungs are like bagpipes. Bagpipes are instrument that we blow in. Inside your lungs, there is something else cool! They are… The bronchial tree! Actually, the bronchi are the tube which appears before the lungs. Have you ever thought of having tree branches in your body? They are __inside__ your lungs. It gets smaller and smaller as it goes deeper to your lungs. Also, you might know this which is the air passes through the bronchi tubes. Let’s see what’s under… Uh, uh, uh. Sorry. Because I just came back from exercise so I am tired. It seems like my breath became harder. I used so much strength to my muscles. I will make sure I will take a deep breath after I finished exercising. There are air sacs called alveoli. Alveoli are surrounded by tiny blood vessels called capillaries. Capillaries are only 1 cell thick. Alveolus is also part of the respiratory system. By the way, ATP, do you know what the word stands for? It stands for adenosine triphosphate in long form. Isn’t it cool? Actually alveoli looks like many huge beans stuck hardly together. The alveoli are placed in the bronchial tree. They are like leaves of plants of the tree. To me, it looks a bit like a broccoli. The diaphragm is under the lungs. The diaphragm is a strong muscle. It is an important part of breathing system. If we relax, the diaphragm will go down. As I’ve already said, then we exercise, we breathe harder because we use a lot of energy. During the cellular respiration the chemical energy is released. The diaphragm is the strongest muscle in the respiratory system. Next, these are some fun facts. Lungs look like the bagpipe because even bagpipe makes sound as lungs do when we breathe out. The right lung is bigger than the left lung. Women and children’s breathing rate is faster than men. We lose half a liter everyday just by breathing. At rest, people take in and breathe out 10 liters of water each. Overall, the respiratory system is a system in our body. It is more interesting than anything. As I’ve told you, there are many parts and parts of the respiratory system. The epiglottis is not really a part of the system but you can include epiglottis as the parts of the respiratory system. The system of this is placed mostly at the top of our body. I mean it is at the top because everything starts from the nose and the mouth which is on our face. Go on breathing! Remember not to stop breathing! **Written by Ji Ae G5** **<span style="display: block; font-family: Calibri; line-height: 18px; margin: 0cm 0cm 10pt; text-align: justify;">Respiratory System and its Functions- Darshan <A fascinating introduction to the Respiratory system and its functions.> Do you know what lungs are? Well, if you don’t I’ll tell you about it. Lungs are sponge like tissues which help you breathe in and out. Lungs are located in your left and right upper body. Lungs are essential. Lungs help your muscles work properly. Lungs are organs which take in oxygen and take out carbon dioxide. Your lungs give oxygen to your cells and blood vessels. Without your lungs you would have no oxygen plus you would die. Oxygen is the main thing that your body needs. ** **<span style="display: block; font-family: Calibri; line-height: 18px; margin: 0cm 0cm 10pt; text-align: justify;">Do you know that our lungs breathe in a gallon of oxygen every minute? Your left lung is smaller than your right lung because your right lung needs to fit in your heart. Your left lung has 2 lobes while your right lung has 3. All the same both of your lungs are important. Your lungs breathe in clean oxygen and breathe out dirty carbon dioxide. Carbon dioxide is important for the plants. Plants breath in carbon dioxide and breathe out oxygen for us to breathe. ** **<span style="display: block; font-family: Calibri; line-height: 18px; margin: 0cm 0cm 10pt; text-align: justify;">The windpipe or the trachea joins the other respiratory tract to the lungs. If you gently touch your throat you can feel your trachea. The bottom of the trachea splits in two branches called bronchi. One enters your right lung and the other enters to the left lung. The bronchial tree’s job is to spread the air from the trachea over a very wide area as quickly as possible. The air passing through the windpipe divides into two branches. These divide into twigs called bronchioles. These twigs open into little sacks called alveoli. We have 300 million air sacs or alveoli in each lung. The alveoli gives our lungs a huge surface for taking oxygen from the air. ** **<span style="display: block; font-family: Calibri; line-height: 18px; margin: 0cm 0cm 10pt; text-align: justify;">Lungs provide the breath of our life. Our lungs are the size of a pair of footballs. They fill our chest from the neck to the ribs. The lungs are protected by our ribs. The lungs are the pickup place for oxygen and send off place for Carbon Dioxide. The lungs are always working. They breathe in oxygen and breathe out carbon dioxide. Blood is pumped into the lungs from the heart through the pulmonary veins and travels to the heart. Oxygen is the fuel that makes all the body process run. ** **<span style="display: block; font-family: Calibri; line-height: 18px; margin: 0cm 0cm 10pt; text-align: justify;">How is air cleaned before it enters our bodies.? Air is filtered by our cillias. Cillias are fine hair-like projections. When you breathe you can’t breathe cold air. Your body would suffocate if you do. The air that you breathe is warmed by blood. Do you know what would happen if you breathe thick air. You would most probably have a running nose. The air that you breath is moistened by your mucus membrane. Do you know what are diaphragms? Diaphragms are muscles which help you breathe. When you inhale your diaphragms inflate and when you exhale your diaphragms deflate. ** **<span style="display: block; font-family: Calibri; line-height: 18px; margin: 0cm 0cm 10pt; text-align: justify;">Do you know that smoking is a very bad thing to do. It mostly affects your lungs. When you smoke it can cause many lung diseases. It can kill you! The more you smoke the more it kills you. Carbon Monoxide is the air that comes out of cigarettes. Alveoli is where gas exchange is performed. Carbon Monoxide prevents hemoglobin from transporting oxygen properly. If you smoke you are replacing half the oxygen in your body with poison! That is why you should never ever smoke. ** **<span style="display: block; font-family: Calibri; line-height: 18px; margin: 0cm 0cm 10pt; text-align: justify;">We have finished the Respiratory System. Now I still have things to tell you!! The main part of the respiratory system is your lungs. Your lungs take in oxygen and breathe out carbon dioxide. Without your lungs you would die. Your lungs breathe in oxygen as quick as it can because all your tissues and muscles need oxygen to work. Our bodies are working properly because of our lungs. After all this I consider respiratory system to be one of the most important system in our bodies.Origanally written by ;Darshan G.5 :D ** Respiratory system What is respiratory system in your body?
 * In our body, there are many systems that make us alive. There is one system that I will tell you is a very important system. It is the respiratory system. The respiratory system is the system that allows you to breathe in and out. We get oxygen from the air that we breathe. Nobody can live without breathing.**
 * Air in our body comes from this place. That is the nose and mouth. This is where the oxygen first enters your body and also where carbon-dioxide leaves. The sinuses help us moisten and heat the air that we breathe. Air can get into our body by the mouth or alcavity. During cellular respiration, carbon-dioxide is released. If you have no nose or mouth, the air cannot get into our body.**
 * The pharynx and trachea is the pass way of oxygen and carbon-dioxide. Air comes from the nose to the trachea then to your bronchi tubes and lungs. Your trachea is held open by incomplete rings of cartilage. When you exercise, you breathe harder because you need food and oxygen to get more energy. If you have no rings your trachea will close off and air cannot get to your lungs.**
 * The trachea splits up into two bronchi tubes. These bronchi tubes get smaller and smaller inside your lungs. These air sacs allow you to take in the oxygen. The left lung is smaller than the right lung because the right lung has 3 lobes but the left lung has 2 lobes. Bagpipes are like our lungs because it expands and contracts when you blow on it. When you relax, the diaphragm does not relax. The diaphragm is an important factor in breathing.**
 * Your alveoli are tiny air sacs that fill up with air/oxygen. The walls of your alveoli are so thin that oxygen or carbon-dioxide can pass through them. The purpose of mucus is to coat the lining of the airway to create a sticky surface that can collect foreign particles from inhaled air. The alveoli are tiny air sacs. Your alveoli are surrounded by capillaries. If you smoke your air sacs will be black.**
 * In summary, the 5 main parts of respiratory system are the nose and mouth, the pharynx and trachea, the bronchi tubes and bronchiole, the alveoli and capillaries network, and the diaphragm. In one day, we lose half a liter of water for breathing. The capillaries in the lungs would extend 1600 kilometers of placed end to end. Each red blood cell contains 280,000,000 hemoglobin molecules. If you have no respiratory system, you won’t be able to breathe.**

** The respiratory systems, and its parts and functions-Radhika **

 * The respiratory system is one of the most important system in your body. The respiratory system helps you breathe oxygen (O) and helps you to exhale carbon dioxide (CO2). The respiratory system has 6 main parts and those are the Larynx, Left Primary bronchi, Trachea, Left lung and Secondary bronchi. The respiratory system is important because if you don’t breathe you will surely die. **


 * The nose helps us smell and breathe and our mouth helps us breathe out CO2 means carbon dioxide and also helps us taste things and eat. This is where oxygen first enters your body and also where carbon dioxide leaves. It is filtered by tiny hairs, and then it is moisturized by mucus. Sinuses help the respiratory system by producing mucus in your nose. **


 * The pharynx is placed before the larynx and the trachea is placed after the larynx, so the larynx is in the middle of trachea and the pharynx and after the trachea is the epiglottis which is the flap of skin which allows food to go to the stomach from the esophagus. This where the air passes from your nose to your bronchi tubes and lungs. Your trachea is held open by “incomplete rings of cartilage.” Without these rings your trachea a might close off and air would not be able to get to and from your lungs. Larynx is a voice box in your throat. **


 * The trachea splits into two bronchi tubes, these two tubes keep splitting up and form your bronchiole. The bronchi tubes split, like three branches, they get smaller inside your lungs. Air flows through bronchi tubes, into your bronchiole. **
 * Alveoli are thin air sacs, you breathe in oxygen. Alveoli are surrounded by capillaries and also are very thin. Sometimes they even burst. **


 * Lungs expand and contract in response to changes in pressure inside the chest cavity. At rest the body takes in and breathes out about 10 liters of air each minute. The right lung as slightly larger than the left one. The highest recorded “sneeze speeds” is 165 km per hour. The surface area of the lungs is roughly the same size a tennis court. The capillaries in the lungs would extend 1,600km if placed end to end. Did you know oxygen rich blood leaves the heart and travels through arteries? Around 500ml of bloods moves from the heart and lungs down to the legs when a person stands up after lying down. So just think how much of oxygen do you breathe in a day. **


 * The respiratory system is one of the most important systems. When we breathe oxygen into our nose, the air that we breathe gets moisturized by “mucus” and filtered by tiny little hairs that are in our nose. We inhale oxygen and exhale carbon dioxide and then we will have breathe good fresh air. **

THE RESPIRATORY SYSTEM-ASIS

Do you know what the respiratory system is? The respiratory system is the system that helps you breath in and out. The main parts of the respiratory system are the lungs. There are 2 lungs in our body. The lungs are important because they get the air in and out of our bodies. The pharynx (throat) is also important. The other thing that is also very important is the trachea (windpipe) because it is the tube in our pharynx that allows the air to reach to the lung.

Did you ever know that the right lung is a little bit bigger than the left lung? The reason for that is because if both the lungs are big, then they won’t be space in your body to fit your heart. The left lung has two lobes and the right lung has three lobes. Our lungs are like bagpipes because when we blow in the air fills in the bag and when you don’t blow all the air that is in the bag goes out, just like our lungs air goes in and out of us.

Do you know what is bad for the respiratory system? Smoking, smoking is the thing that is very bad for the respiratory system and the lungs. The reason for that is because smoking can cause lung can cause lung sickness, lung cancer, and lung disease. Smoking also poisons lots of the cells of our body. Smoking is also very bad because it has carbon monoxide and the same things as the car resources. Smoking also makes our lungs brown and rotten.

Do you know why you breathe harder when you exercise? It is because your heart rate is becoming faster and your body is working faster which makes you breath harder and faster. Do you know we lose half a liter of water in our body just because of breathing? Your alveoli (air sacs) are surrounded by tiny blood vessels which are called the capillaries.

Sinuses can also help with the respiratory system. When air comes in your nose, it gets filtered up with the tiny hair and moised with the mucus in your nose. Air can also get in your body through the nose. A breathing rate is faster in the children and women than in men. A person at rest usually breathes between 12 and 15 minutes. There is a tiny flap of skin in your trachea called the epiglottis which tells the food nd the air which way to go.

Did you know that respiration equals food plus oxygen which equals energy and carbon dioxide? The ways that you can take care of your lungs is by not smoking and try not to breathe bad air because all of those things destroy the lungs and sometimes also make your life shorter, it also makes it hard for you to breath. So that is all about the respiratory system

== **<span style="font-family: 'Calibri','sans-serif'; font-size: 12pt;">Lungs are in our body. They help us breathe. They are connected with hearts. Respiratory System has many parts like diaphragm, bronchial trees, trachea, larynx and more. The main part in our respiratory system is lungs. ** ==

== **<span style="font-family: 'Calibri','sans-serif'; font-size: 12pt;">Lungs are in our chest. When we breathe in the air goes through larynx then trachea and then bronchi and last to our lungs. Veins give blood to the lungs and arteries take away the blood and give the blood to the heart. When the air comes to our body diaphragm goes down and when the air goes out diaphragm goes up. When we breathe in oxygen come in and when we breathe out carbon dioxide goes out. ** ==

== **<span style="font-family: 'Calibri','sans-serif'; font-size: 12pt;">If the blood is purple color it means carbon dioxide is inside. When we breathe out carbon dioxide goes away, so blood become red color that means it has oxygen. This happens, because if this didn’t happen we would have died. Our nose and mouth breathe in and out. ** ==

== **<span style="font-family: 'Calibri','sans-serif'; font-size: 12pt;">You see the lungs and everything helps us breathe. These things are called ‘The respiratory system.’ We have to thank these things. Lungs help us breathe! Don’t forget! ** ==

== **<span style="font-family: 'Calibri','sans-serif'; font-size: 12pt;">Right lung is bigger than left lung, because if left lung was same size as right lung there will be no space for the heart. After we exercise when we breathe in we breathe harder, because we are tired and our heart beats faster. We get oxygen from everywhere. Abbreviation for adenosine triphosphate is ATP. Lungs are like bagpipes, because they keep oxygen inside. When we relax our diaphragm it will stay calm and still. The purpose of the mucus is when we breathe in the mucus stops the dust going through our nose. Energy is released during cellular respiration. Respiration is equal to food, oxygen and energy. ** ==

It contains the lungs and its parts like trachea, bronchi, bronchial tree, and diaphragm etc. There are two lungs in the human body. The lungs are like sponge. These are situated within the thorax, protected by the ribs.

The lungs are very important, because they supply the blood with oxygen, through alveoli. Alveoli are tiny little tubes formed in clusters, like little bunches of grapes. When we breathe in, these fill with air and take oxygen to the blood. Alveoli are filled with capillaries. Capillaries are one cell thick. He trachea is a tube next to the esophagus but it takes in are. Before that there is the larynx witch contains vocal cords.

<span style="display: block; font-family: Times New Roman; margin: 0cm 0cm 0pt; text-align: justify; text-indent: 36pt;">Esophagus is the tube that connects mouth to your stomach. It carries food to our stomach. There is another tube that is connected to the lungs. It is called trachea. Our lungs work hard like the heart. They are working even when we are asleep. They take in air. The right side lung is slightly bigger than the left side lung, because its space is given to the heart. The lungs are similar to bag pipes, because they can expand and keep air in. The lungs can expand and contract by the diaphragm. The diaphragm moves toward the chest cavity. When we exercise, we breathe harder to increase the amount of oxygen available in our body.

<span style="display: block; font-family: Times New Roman; margin: 0cm 0cm 0pt; text-align: justify; text-indent: 36pt;">Oxygen is what we breathe in.
