Answer 1

simply saying, heart’s function is to…

take the blood from vena-cava(both superior and inferior)

pump it through the pulmonary artery to the lungs

after the lungs oxygenate the received blood, blood is sent to the heart through the pulmonary vein

the heart then pumps the oxygenated blood for the whole body through the aorta

Answer 2

main function of heart is to pump oxygenated blood from lungs to body and deoxygenated blood from body to lungs and keeps oxygenated and deoxygenated blood separate.
