Function of Heart is :-

Left ventricle receive oxygenated blood from the lungs via pulmonary vein. During this collection the left atrium relaxes. It then contracts while left ventricle expands , so blood is transferred to it. As the left ventricle contracts, the blood is then pumped out for circulation in the body. Deoxygenated blood enters to the right atrium as it expands. When the right atrium contracts the corresponding lower chamber, i.e. the right ventricle dilates. Deoxygenated blood thus, enters in it which in turn is pumped to lungs for oxygenation.

Valves are the muscular flaps that prevent backflow of blood. Septum is a muscular wall that prevents mixing of oxygenated and deoxygenated blood.
