Question

Below is a picture of a structure of the heart. What is the best description of the function of this structure?

Answer 1

In simple term, Heart can be stated as the organ which pumps the blood and circulates the blood throughout the body and  It prevents the back flow of blood from the left ventricle into the left atrium.

Explanation:

The Heart spreads the blood to our human body through two ways the right side and left side.

Right side:

• The right atrium receives the deoxygenated  blood from our body than the right atrium contracts and then blood passes to the right ventricle.

Left side:

• To the other side of  the pulmonary vein, the newly oxygenated blood moves to the left atrium.
• Then the left atrium contracts and it pushes the blood to the left ventricle, then left ventricle becomes full it then contracts and pushes the blood back to the body.
