ANATOMY

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: -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-3: -Tricuspid Valve Prevents the back flow of blood from the right ventricle to the right atrium.

Detailed explanation-4: -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.

Detailed explanation-5: -Correct answer: The tricuspid valve prevents backflow from the right ventricle into the right atrium. The bicuspid valve prevents backflow from the left ventricle into the left atrium. The semilunar valves prevent backflow into the ventricles from the aorta and pulmonary arteries.
