Mammals and birds have double circulation.
The pathway of blood through the heart is as follows:
- The deoxygenated blood from the body is received in the right atrium from the vena cava and enters the right ventricle through a tricuspid valve. It enters the pulmonary artery through the semilunar valve and goes to pulmonary circulation.
- The oxygenated blood from the lungs is received in the left atrium from the pulmonary veins and enters the left ventricle through the bicuspid valve. It enters the aorta through a semilunar valve and goes to the systemic circulation.
