Question

explain the process of double circulation with the help of suitable diagram explain

Answer 1

The process of double circulation refers to the flow of blood from heart twice. When it enters from Pulmonary veins in left atrium and then went to all body parts and then blood come from other all body parts which is deoxygenated in right atrium and is sent back to the lungs for getting oxygenating. So it is a double circulation.

hope it helps^_^

Answer 2

Answer:

The pulmonary vein brings the oxygenated blood from the lungs in the left atrium of the heart.

The left atrium contracts and pumps blood into the left ventricle through the valve.

On contraction of left ventricle, the oxygenated blood enters the largest artery aorta. The blood travels from aorta to the smaller arteries and distributed to the organs of whole body.

Superior vena cava collects blood from the upper parts of the body and inferior vena cava collects from the lower parts of the body and carry it to the right atrium of the heart.

The right atrium pumps deoxygenated blood into the right ventricle through the valve.

When the right ventricle contracts, the deoxygenated blood enters the lungs through the pulmonary artery where it is purified.
