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: -Heart valves control the flow of blood so that it moves in the right direction. The valves prevent blood from flowing backward. The heart has four valves. The tricuspid valve separates the right atrium and right ventricle.
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.
