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: -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.
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.
Detailed explanation-4: -Arteries are thick-walled when compared to thin-walled veins. Arteries for this reason carry oxygenated blood which comparatively has high pressure. Since the blood pressure In this region is high, the blood flows only In one direction.
