ANATOMY

Detailed explanation-1: -Tricuspid valve: Allows blood to pass from the right atrium to the right ventricle; prevents blood from flowing back into the right atrium as the heart pumps (systole).

Detailed explanation-2: -This backflow of blood is prevented by valves. Tricuspid valve prevents backflow of blood from right ventricle to right atrium. Bicuspid valve prevents backflow of blood from left ventricle to left atrium.

Detailed explanation-3: -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). The valve flaps then close tightly to prevent the blood from moving backward.

Detailed explanation-4: -Final answer:The valve which prevents back flow of blood in the veins is Semilunar valve.

Detailed explanation-5: -The tricuspid valves job is to allow blood flowing into the heart from the body to flow to the right ventricle where it’s pumped to the lungs for oxygen. If the tricuspid valve is leaky, blood can flow backwards, causing the heart to pump harder.
