Answer 2

Explanation:

A heart consists of four chambers. Upper two chambers are called atria and lower two chambers are called ventricles. It consists of four valves[bicuspid valve, tricuspid valve,semilunar valves(2)].It also consists of a pulmonary artery, a pulmonary vein,vena cava and aorta.

Oxygenation of blood

The deoxygenated blood enters the right atrium through vena cava and then enters into left ventricle through tricuspid valve and then goes into the lungs through pulmonary artery.

After blood gets oxygenated,it enters the left atrium through pulmonary vein and then enters into our left ventricle through bicuspid valve and the goes into our body through aorta.
