Detailed explanation-1: -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. When the right atrium fills, the tricuspid valve opens, letting blood into the right ventricle.

Detailed explanation-2: -The flow of blood through the blood vessels and chambers of the heart is controlled by valves. The four main valves are: 1. Tricuspid valve: This separates the right atrium and right ventricle.

Detailed explanation-3: -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-4: -The tricuspid valve sits between the heart’s two right chambers. The tricuspid valve consists of three thin flaps of tissue (called cusps, or leaflets). These valve flaps open to let blood flow from the upper right chamber (right atrium) to the lower right chamber (right ventricle).

Detailed explanation-5: -The right atrioventricular valve has three cusps, and is therefore called the tricuspid valve, while the left atrioventricular valve has two cusps, and is known as the bicuspid or mitral valve-mitral because it is said to resemble a bishops mitre.
