Which valve is situated between the right atrium and ventricle and is composed of three flaps?
- A.
Mitral Valve
- B.
Semilunar Valve
- C.
Tricuspid Valve
Correct Answer
C. Tricuspid ValveExplanation
The tricuspid valve is located between the right atrium and right ventricle. It has three cusps, or flaps, that open and close to control blood flow. This valve ensures that blood flows in one direction—allowing blood to move from the atrium to the ventricle but preventing backflow during ventricular contraction. If the tricuspid valve is damaged or fails to function properly, it can lead to conditions such as tricuspid regurgitation, where blood flows backward, leading to complications such as heart failure and increased pressure in the veins.Rate this question:

Which valve is situated between the left atrium and ventricle?
- A.
Tricuspid Valve
- B.
Mitral Valve
- C.
Semi-Lunar Valve
Correct Answer
B. Mitral ValveExplanation
The mitral valve is located between the left atrium and left ventricle. It consists of two flaps that open and close to regulate blood flow. When the left atrium contracts, the mitral valve opens, allowing oxygen-rich blood to flow into the left ventricle. Upon ventricular contraction, the valve closes to prevent blood from flowing backward into the atrium. If the mitral valve malfunctions, it can result in conditions like mitral regurgitation, where blood leaks backward, or mitral stenosis, where the valve becomes narrowed, leading to reduced blood flow.Rate this question:
