Detailed explanation-1: -Tricuspid valve: This valve has three leaflets. They allow blood to flow from the right atrium to the right ventricle. They also prevent blood from flowing backward from the right ventricle to the right atrium.
Detailed explanation-2: -Valves maintain direction of blood flow 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: -The tricuspid valve ensures that blood flows from the right atrium to the right ventricle. It also prevents blood from flowing backward between those two chambers.
Detailed explanation-4: -Heart Valve Structure and Function The valves ensure unidirectional blood flow through the heart. Between the right atrium and the right ventricle is the right atrioventricular valve, or tricuspid valve. It typically consists of three flaps, or leaflets, made of endocardium reinforced with additional connective tissue.
Detailed explanation-5: -Valves function to prevent backflow of blood and maintain a unidirectional circulation of blood within the body. The tricuspid valve separates the right atrium from the right ventricle whereas the bicuspid valve separates the left atrium and left ventricle.
