Detailed explanation-1: -The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
Detailed explanation-2: -A common type of valve is a check or backflow preventer. These valves are unidirectional valves and allow the water to flow in one direction only.
Detailed explanation-3: -The blood that is meant to leave the ventricles to travel to the body is supposed to be prevented from flowing in the wrong direction by the parts of the aortic and pulmonary valves called the cusps. The cusps help the valves create a tight seal, which helps blood flow in the correct direction.
