Answer 2

Bicuspid valve guards opening of left atrium into left ventricle.

Answer:

Option 1 is right.

Explanation:

BICUSPID VALVE:

• It is also called mitral valve.

• It is present between left atrium and left ventricle.

• The bicuspid valve prevents the backward flow of blood from left ventricle to left atrium.

TRICUSPID VALVE:

• It is present between right atrium and right ventricle.

• It regulates the flow of blood from right atria to right ventricle and prevents its backward flow.

SEMILUNAR VALVES:

• These are present at the base of pulmonary artery and also at the base of aorta.

• Semilunar valves present in pulmonary artery prevent the backward flow of blood from pulmonary artery into right ventricle.

• Semilunar valves present in aorta , regulate the blood flow from left ventricle into aorta.
