Answer:

Mechanism of blood circulation in heart:-

(a) Right auricle receives blood from the whole body through two major veins.

(b) On contraction, right auricle sends the blood into the right ventricle.

(c) When right ventricle contracts, this deoxygenated blood is sent to lung for oxygenation (absorption of oxygen from air in the lung).

(d) Left auricle receives oxygenated blood from the lung and sends it to left ventricle.

(e) On contraction, left ventricle pushes this oxygenated blood in the main artery called aorta.

(f) Aorta moves downward in the body and has branches to each and every organ of the body.
