Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	prevents blood from returning to the right atrium.
B	prevents blood from returning to the left atrium.
C	prevents blood from returning to the right ventricle.
D	prevents blood from returning to the left ventricle.

Explanation:

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: -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-3: -right atrioventricular valve (or AV valve) controls blood flow from the right atrium to the right ventricle.

Detailed explanation-4: -There are two atrioventricular valves, Mitral (Bicuspid valve) and Tricuspid valve. These valves maintain the flow of blood from atrium to ventricle and do not allow the backflow of blood from ventricles to atrium.
