❤️ Valve Between Right Atrium and Right Ventricle ❤️

The human heart has four chambers — two atria (upper chambers) and two ventricles (lower chambers). Valves are present between these chambers to ensure one-way blood flow.

Question: The valve between the right atrium and right ventricle is —

✅ Correct Answer: (b) Tricuspid valve

The tricuspid valve is located between the right atrium and the right ventricle. It has three cusps (leaflets), which is why it is called “tri-cuspid.”

Function:

• Allows blood to flow from the right atrium to the right ventricle
• Prevents backflow of blood into the right atrium during ventricular contraction

Why are the other options incorrect?

(a) Bicuspid valve → Also known as the mitral valve. It is located between the left atrium and left ventricle.

(c) Tetracuspid valve → This is not a normal anatomical valve in the human heart.

(d) Monocuspid valve → The heart does not have a single-cusp valve between chambers.

✅ Exam Point:
Right side AV valve → Tricuspid valve
Left side AV valve → Mitral (Bicuspid) valve
