MEDICAL PHYSIOLOGY

Detailed explanation-1: -Heart valves open and close to allow for proper blood flow. Your valves ensure that blood flows only in one direction. These valves are: Aortic valve connects your left ventricle and aorta (large artery that carries blood throughout your body).

Detailed explanation-2: -As the heart pumps blood, a series of valves open and close tightly. These valves ensure that blood flows in only one direction, preventing backflow.

Detailed explanation-3: -Then they close, so the blood cannot flow backwards into the atria. With this system, blood always flows in only one direction inside the heart. There are also valves at the bottom of the large arteries that carry blood away from the heart: the aorta and the pulmonary artery.

Detailed explanation-4: -The blood flow in one direction is vital in order to go prevent backwards and thus prevent mix up of oxygenated and deoxygenated blood in the heart. The mixing of oxygenated and deoxygenated blood may lead to heart failure.
