ANATOMY

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.

Detailed explanation-2: -Tricuspid Valve Prevents the back flow of blood from the right ventricle to the right atrium.

Detailed explanation-3: -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-4: -Final answer:The valve which prevents back flow of blood in the veins is Semilunar valve.
