Question

Where are the following located?
(i) Mitral valve
(ii) Tricuspid valve

Answer 1

(i) The mitral valve

1. Mitral valve is also known as bicuspid valve or left atrio-ventricular valve.
2. LOCATION: The mitral valve is present between the left atrium and the left ventricle.
3. FUNCTION: It prevents the backflow of blood from left ventricle to left atrium during ventricular contraction.

(ii) The tricuspid valve

1. LOCATION: The tricuspid valve is located between the right atrium and right ventricle. Hence it is also known as the right atrio-ventricular valve.
2. FUNCTION: The tricuspid valve prevents the backflow of blood from right ventricle to right atrium during ventricular contraction.
