The **circulatory system** is an [|organ system] that passes nutrients (such as [|amino acids], [|electrolytes] and [|lymph]), gases, hormones, [|blood] cells, etc. to and from [|cells] in the body to help fight diseases and help stabilize [|body temperature] and [|pH] to maintain [|homeostasis]. This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the **cardiovascular system**, which distributes blood,[|[1]] and the **[|lymphatic system]**,[|[2]] which distributes [|lymph]. While humans, as well as other [|vertebrates], have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, [|veins] and [|capillaries]), some [|invertebrate] groups have an open cardiovascular system. The most primitive animal phyla lack circulatory systems. The lymphatic system, on the other hand, is an open system. Two types of fluids move through the circulatory system: blood and lymph. The blood, heart, and blood vessels form the cardiovascular system. The lymph, lymph nodes, and lymph vessels form the [|lymphatic system]. The cardiovascular system and the lymphatic system collectively make up the circulatory system.

The main components of the human cardiovascular system are the [|heart], the veins, and the [|blood vessels].[|[3]] It includes: the [|pulmonary circulation], a "loop" through the [|lungs] where blood is oxygenated; and the [|systemic circulation], a "loop" through the rest of the body to provide [|oxygenated] blood. An average adult contains five to six quarts (roughly 4.7 to 5.7 liters) of blood, which consists of [|plasma], [|red blood cells], [|white blood cells], and [|platelets]. Also, the [|digestive system] works with the circulatory system to provide the nutrients the system needs to keep the [|heart] pumping. By:Jinjoo Kim

The circulatory system-Asis g.5

The parts and the jobs of the circulatory system.In the circulatory system they're are the three main parts that are very important which are called the heart ,the blood vessels, and also the blood. The heart keeps you alive and transports your blood and the heart brings in the old blood and recycles it,the blood vessels carry the blood, and the blood carries the red and white blood cells.So that is some information on the main parts of the circulatory system.

The heart and the main part the main parts of the heart.The heart contains of the atria which is the first part and is known as the receiving chambers which receive the blood and the cellular waste.Secondly they're is the ventricils which is known as the pumping chambers which pumps your heart and when your heart pumps it makes a sound like lub-dup.Thirdly they're is the is the valves which is known as the control flow that controls the heart flow.Lastly they're is the septum which divides the heart.This is about the main parts of the heart.

The types of blood vessels in our body that transport the blood.The types of blood vessels in our body are the arteries which is used for carrying blood away from the heart.The veins bring recycled blood into the heart which adds to the cellular waste. They are also the capillaries which is known as the "distribution pipes". So that is some of the main things about the types of blood vessels and what they do and also all about the parts that they contain of.

Fast facts on the circulatory systems.In our body the plasma makes up 55 percent of the blood volume and the solids make up the other 45 percent of the blood volume.The blood plasma is 97 percent of water and three percent of solid. The blood solids contain of the red blood cells and the white blood cells it also has the platelets.These are the facts on the circulatory system which are important things that are body contains of.

Now this is all of the circulatory system which keep you alive. All together the main things are the types of the blood vessels,red and white blood cells and the heart and also the blood.The arteries, capillaries and the veins. So this is the end of the information all about the different parts in the circulatory system.This is all the hard work that our body does so are body is like a machine.

circulatory systems-Radhika Circulatory system

The 3 main parts of the circulatory systems are the... 1.heart 2.blood vessel 3.blood

The parts of heart Parts of heart are the atria which receive cambers, the ventricles that pump cambers, the valves which control flow, and lastly the septum.As you know the heart pumps like this lup-dup lup-dup and if it stops you DIE.

Types of blood in our body There is arteries which carry blood away from the, aorta is the largest artery, veins they carry blood back from heart, veins contain valves, the “vena cava” is the largest vein, capillaries are known as the “Distribution Pipes”.

The composition of blood The plasma (Fluid) makes up 55% is of blood volume and the solid (cells) makes up 45% of the volume.

This is about blood plasma 97% of water and others are 3% antibodies and proteins, nutrients and wastes.

Now this is about blood solids In blood solids there are red blood cells, carry oxygen, they contain Hemoglobin and white blood cells fight bacteria and other mvaders, and last one platelets, they control the blood clotting process. Circulatory system keeps you clean.

So did you see how our body works and how the heart does, so this was the circulatory systems.

// Do you know how blood in our body circulates? In the circulatory system there are three main parts in our body that are very important; heart, blood vessel and blood. // Starting from our heart, poor in oxygen blood is pumped from right atrium to right ventricle and then to lungs for re-oxygenation. Rich in oxygen blood is passed to the left atrium and then to left ventricle. The pumps the rich in oxygen blood to the body by arteries and capillaries. Both are two types of blood vessels that carry blood away from the heart. The third type of blood vessel is veins that carry blood back to the heart. In our blood, there are 55% blood plasma, a liquid part. Blood plasma contains 97% water, 3% others such as antibodies, proteins, nutrients and waste. There are three types of blood cells. They are white blood cells, red blood cells and platelets. White blood cells help the body fight infection. Red blood cells look like little donuts. Red blood cells deliver oxygen to cells. Platelets look like little thorny or spiky ovals. Platelets are fragments of the cells. Platelets survive for eight to ten days and help blood to stop bleeding. Now, you know that circulatory system is very important to keep us alive. Everyone should exercise to keep the healthy heart and body.

The Parts and Functions of a Circulatory System



There are several systems in our human body. The circulatory system is one of it. This system helps the body send blood around. This also means it makes the heart pump, continually. This system is doing an important job in our body. It also has different parts, just like other systems in our body. So let’s look at the different parts and the functions of it.

The blood is one of the main parts in the circulatory system. It is a liquid tissue that moves food, oxygen, waste, and hormones to and from body cells. The blood sends foods and nutrients to all parts of our body. In the blood, there are substances called “platelets”, which help clot the blood from a cut or a wound. When the blood clots, it becomes dry, and hard.

The heart also does an important job in the circulatory system. There are 4 chambers in our heart. The atrium is either of the upper spaces in the heart, which helps blood pass through things in the ventricles. The ventricle is either of the lower spaces in the heart, which pumps blood to our body. The flow of blood through our body is called “circulation”, and that is why this system is called the “Circulatory System”.

There are 3 blood vessels in our body. There are the artery, vein, and capillary. Arteries carry blood away from the heart. Veins carry blood back to the heart. Capillaries allow cellular transportation, and they are only 1 cell thick.

This is a small explanation on how the system runs. When we breathe in, the oxygen goes to our lungs. Then, the blood that contains oxygen will go to our heart. After that, it will go around our body, and pass oxygen to all parts of our body. Lastly, it will come back to our heart (because it will now be an old blood), and repeat this cycle over, and over, and over again. When our body repeats this cycle, our heart beats, and we can stay alive.

The body sends blood around the body, and to the heart. Other systems of our body break down foods, or move muscles in our body. The red blood cells and white blood cells fight against germs, and attract oxygen to transport it to body cells. Not only humans have this system, but also other living things have this too. People and animals depend on each other, just like the systems in our body do.

This is my essay--Ji Ae G5 The Cool Circulatory System- Ji Ae G5

The circulatory system is a system of the bloods inside our body. They look cool and amazing. There are 3 main types of the circulatory system. The 3 types are the heart, the blood vessels, and the blood. In the circulatory system, the types are very important. So if we didn’t have the heart, the vessels, and the blood, we will not be alive. So in the essay, it will give you some facts about the 3 types.

<span style="font-family: 'Calibri','sans-serif'; font-size: 12pt; margin: 0cm 0cm 0pt;">First of all, the function of the heart is to make us alive. The heart has a big job. It always pumps. The sound of the heart pumping is lub- dub. If the heart doesn’t pump, we will be dead immediately. That’s how much the heart’s job is important. The parts of the heart are the atria, the ventricles, the valves, and the septum. They each has a job. Maybe the heart is the largest part of our body. The heart has 4 chambers.

<span style="font-family: 'Calibri','sans-serif'; font-size: 12pt; margin: 0cm 0cm 0pt;">The blood vessels are also one of the main parts. There are also types of vessels. The types are the arteries, veins, and capillaries. Each of the parts have each function. Arteries carries blood away from the heart, veins carries blood in the heart. Lastly, capillaries are a cell thick!

<span style="font-family: 'Calibri','sans-serif'; font-size: 12pt; margin: 0cm 0cm 0pt;">Blood can be in plasma and in solid. Plasma is name as fluid too! Solids are also named as cells! The fluid makes up 55% and the cells make up 45%. The blood plasma is 9% water and the other 3% is antibodies, proteins, nutrients, and wastes. The blood solids may be the red and the white blood cells. In the blood solids, there are platelets too! Lastly, they all have their own job.

<span style="font-family: 'Calibri','sans-serif'; font-size: 12pt; margin: 0cm 0cm 0pt;">In conclusion, all of the parts in the circulatory system are very important parts of our body system. Remember that you can’t live without the parts that I’ve told you. For example, imagine you were born without a heart. You will be dead just a second after you were born. Our body is 97% water. One cool thing that is really true is that the capillaries are just a cell thick! Lastly, they all are so important!

<span style="display: block; font-family: Calibri; font-size: 14pt; line-height: 115%; margin: 0cm 0cm 10pt; text-align: center;">The circulatory system <span style="font-family: Calibri; font-size: 14pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 36pt;">The heart, the blood vessels, and the blood are the three main parts of the circulatory system. The circulatory system helps passing oxygen, nutrient and waste to body cells.

<span style="font-family: Calibri; font-size: 14pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 36pt;">The heart contains four chambers. The upper two chambers are called atria. They are receiving chambers. The lower two chambers are called ventricles. They are pumping chambers. The valves between atrium and ventricle control blood flow. The heart pumps low-oxygen blood to the lung and high-oxygen blood to the body.

<span style="font-family: Calibri; font-size: 14pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 36pt;">The blood vessels that send high-oxygen blood to the body are called arteries. The largest artery is the Aorta. The blood vessels that send low-oxygen blood to the heart and lung are called veins. The largest vein is the Vena Cava. The arteries and veins are connected by the capillaries, known as the “Distribution Pipes.”

<span style="font-family: Calibri; font-size: 14pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 36pt;">The blood contains 97% water. The other 3% are blood cells, antibodies, protein, nutrients and wastes. Red blood cells absorb oxygen from the lung and transport it to every cell. White blood cells help us fight germs. Platelets are tiny pieces of blood cells that help blood to clot.

<span style="font-family: Calibri; font-size: 14pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 36pt;">Respiratory system is very important because if we lose this system, we will die. by:Pat g.5

Circulatory System

The Circulatory system and its functions.

There are 4 chambers in a heart and that makes up the part of the circulatory system. The parts of the circulatory system are the atria, ventricles, valves and, the septum. The atrium is the chamber that receives blood. The Ventricles is the pumping chamber. It pumps blood. Valves are a chamber that controls the flow of blood. Septum is a line that divides the heart into 4 chambers.

Now let’s look at the types of blood cells. There are 3 types blood cells. The arteries, veins, and capillaries. The artery carries blood away from the heart, and to your body. The veins carry blood to the heart. It contains valves. The “Vena Cava” is the biggest vein. The “Aorta” is the biggest artery. Capillaries are also known as the “distribution pipes”. A capillary is 1 cell thick. A capillary is very special because it allows circulation in your body.

Let’s see the waters in our body. There are 2 types of water in our body. Plasma and cells. Plasma is fluid. There is 55 % of plasma in our body. Cells are solid. There is 45 % of cell water in our body. In the blood “plasma”, There is 97% water and 3% other(Antibodies, protein, wastes, and nutrients).

Now let’s see what type of cells carry out which functions. The red blood cell carries oxygen in and out. The white blood cells act like soldiers. They fight bacteria. Platelets controls blood in the clotting process. Clotting is when blood comes out. Blood is replaced, through the heart. It’s a bit like a recycling factory.

This is the circulatory system and their functions. There are more to the circulatory, but this is the main information. The water in our body. I hope you understand my essay.

This is my essay Bloom Circulatory system

The parts of the circulatory system and its function.

I will tell you about the circulatory system. The circulatory system has many parts. One is the heart, second is the blood vessel and third is the composition of blood. These are types of the things I will tell you. I will tell you more.

The heart is an important part of the body. It pumps blood to the body. It needs things to help them. The ventricles are the pumping chamber. The atria are receiving chambers. Valves control flows of blood in our body. Septum divides the heart into four chambers. They help the heart pumps blood.

The blood vessels are the important and they also help the heart. They are connected to the heart. The arteries carry blood away from the heart. The veins carry blood away from the heart. The capillaries are the smallest pipes that hold on to the arteries and veins.

The plasma fluid makes up 55 %of the blood volume. The solid cells make up 45% of your blood volume. 97% is water and 3% are others. They are 2 types of main cells in our body. Red blood cells carry oxygen. The white blood cells is the cops that get all germs in our body.

**// Circulatory System Infor. – Jojo G5 //** There are many parts of circulatory system, but there are 3 main parts of the circulatory system. The 3 main parts are the hearts, blood vessels and blood.

Our heart has many parts, like the Atria, Ventricle, Valves and the septum. Atria is the receiving chamber. The Ventricle is the pumping chambers. The Valves controls Flow and the septum divides the heart.

The blood vessels are divided into different types. The Arteries carry blood away from the heart and also the Aorta is the largest artery. Veins carry blood back to the heart, veins contain valves. The vena cava is the largest vein. Capillary is known as the “Distribution pipes”.

The blood is made out of 2 things. They are plasma and solids. The plasma (Fluid) makes up 55 % of the blood volume. The solids (Cells) makes up 45 % of the blood volume. When this 2 things are together, they became blood.

Blood plasma is also one of the circulatory system. The blood plasma made out of 97 % water. Antibodies, Proteins, Nutrients and wastes are 3 %.

Blood solids consists red blood cells, white blood cell and platelets. The red blood cells carries oxygen containing Hemoglobin. White blood cells attack bacteria & other invaders, and platelets control the blood clotting process.

CIRCULATORY SYSTEM-YOSHITA (Circulatory system is the main part of our body) The Circulatory system, also known as the cardiovascular system, has several functions. These functions include: the transport of substances to and from the cells, maintenance of body temperature, and maintenance of pH as part of homeostasis. The circulatory system of all vertebrates, including humans, is a closed system, meaning the blood is not meant to leave the system. The primary components of the system are the heart, blood and blood vessels.

Circulatory System is the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. The circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature. Also, when foreign substances or organisms invade the body, the circulatory system quickly sends disease-fighting elements of the immune system, such as white blood cells and antibodies, to places under attack. In the case of injury or bleeding, the circulatory system sends clotting cells and proteins to the affected site, which quickly stop bleeding and promote healing. The heart, blood, and blood vessels are the three main elements that make up the circulatory system. The heart is the engine of the circulatory system. It is divided into four chambers, the right atrium, the right ventricle, the left atrium, and the left ventricle. The walls of these chambers are made of a muscle called myocardium, which contracts to pump blood. The pumping action of the heart occurs in two stages for each heartbeat. Diastole, when the heart is at rest, and systole, when the heart contracts to pump deoxygenated blood toward the lungs and oxygenated blood to the body. There are typically about 60 to 90 beats per minute. If the heart stops pumping, death usually occurs within four to five minutes. Blood consists of three types of cells, red blood cells that carry oxygen, disease-fighting white blood cells, and blood-clotting platelets, which are all carried through plasma. Plasma is yellowish and consists of water, salts, proteins, vitamins, minerals, hormones, dissolved gases, and fats. Three types of blood vessels make a network of tubes throughout the body. Arteries carry blood away from the heart, and veins carry it toward the heart. Capillaries are tiny links between the arteries and the veins where oxygen and nutrients spread to body tissues. The inner layer of blood vessels is lined with cells that create a smooth passage for the transfer of blood. This inner layer is surrounded by connective tissue and smooth muscle that help the blood vessel to expand or contract. Blood vessels expand during exercise to meet the increased demand for blood and to cool the body. Blood vessels contract after an injury to reduce bleeding and also to conserve body heat.
