The organ system of human beings and other animals which is responsible for the transport of materials inside the body is called circulatory system. The various organs of the circulatory system in humans are: Heart, Arteries, Veins and Capillaries.

Blood is also considered a part of the circulatory system. So, the human circulatory system consists of the heart, The circulatory system essay, veins, capillaries, and blood.

In the circulatory system, the heart acts as a pump to push out blood. The arteries, veins and capillaries act as pipes or tubes through which the blood flows. These tubes which carry blood are called blood vessels.

Thus, there are three types of blood vessels in the human body: We will now describe all the parts of the circulatory system in detail.

The heart is roughly triangular in shape. It is made of special muscle called cardiac muscle. The upper two chambers of heart are called atria singular atriumand the lower two chambers of heart are called ventricles.

The two atria receive blood from the two main veins. And the two ventricles transport blood to the entire body and the lungs. The left atrium is connected to the left ventricle through a valve V1.

Similarly, the right atrium is connected to the right ventricle through another valve V2. These valves prevent the backflow of blood into atria when the ventricles contract to pump blood out of the heart to the rest of the body.

This is because when the ventricles contract, the valves V1 and V2 close automatically so that the blood may not go back into atria.

The job of heart is to pump blood around our body. All the atria and ventricles of the heart contract and relax expand at appropriate times and make the heart behave like a pump. Since ventricles have to pump blood into various organs with high pressure, they have thicker walls than atria.

The chambers of the heart are separated by a partition called septum. The arteries, veins and capillaries are a kind of thin pipes or tubes through which blood flows in the body. Arteries, veins and capillaries are called blood vessels. Arteries are the thick walled blood vessels which carry blood from the heart to all the parts of the body.

Arteries have thick walls because blood emerges from the heart under high pressure. Arteries are found in the whole of our body. The main artery called aorta is connected to the left ventricle of the heart through a valve V3.

The main artery carries oxygenated blood from the left ventricle to all the parts of the body except the lungs. Another artery called pulmonary artery is connected to the right ventricle of the heart through another valve V4.Circulatory System - Circulatory System The Circulatory System is a transportation and cooling system for the body.
