2. Pumping of oxygenated blood brought to it from the lungs by the pulmonary vein through its left auricle and left ventricle via the aorta to the entire body so that all the cells get the required oxygen for its metabolism and respiration.

Answer 2

Function of heart

Explanation:

1. Heart is a pumping organ that helps in blood circulation and provide nutrients to the tissues throughout the body.
2. The circulation takes place through pulmonary and systemic circuits.
3. During pulmonary circulation,the deoxygenated blood leaves right ventricle and enters the lung through pulmonary artery and then return as oxygenated blood to the left atrium through pulmonary veins.
4. In systemic circuit, the oxygenated blood enters the arteries from aorta where it supplies into the tissues and provide oxygen. Deoxygenated blood then again enters the veane cavae through veins.
