Describe the function of the heart.

Answer :

The heart is an organ act as a pump for the transport of blood and various other substances.

The human heart is divided into four chambers. The upper two chambers are called right and left atrium and the lower two chambers are called the right and left ventricles.

The right atrium receives the blood rich in carbon dioxide from the body. Blood from right atrium enters the right ventricle, which contracts and pumps the blood to the lungs.

On the other hand, blood from the lungs returns to the left atrium. From the left atrium, blood enters the left ventricle.

Left ventricle contracts and pumps the blood to all parts of the body. Hence, the rhythmic contraction and expansion of various chambers of the heart maintain the transport of oxygen to all parts of the body.
