The heart functions as a pump in the circulatory system to provide a continuous flow of blood throughout the body. ... The systemic circulation then transports oxygen to the body and returns carbon dioxide and relatively deoxygenated blood to the heart for transfer to the lungs.

functioning of heart
the heart consist of four chambers, the two atria or auricles and two ventricles work together as a team. the atria or auricle gets fill with blood and then dumps it into ventricles. the ventricles then squeeze while pumping blood out of the heart .
while the ventricles are squeezing ,atria refill and get ready for next contraction. the blood from heart is transferred to rest of the body through artery
