Match the items given in Column I with those in Column II and select the correct option given below:
Column I Column II a. Tricuspid valve 1 Between left atrium and left ventricle b. Bicuspid valve 2 Between right ventricle and pulmonary artery c. Semilunar valve 3 Between right atrium and right ventricle
Match the items given in Column I with those in Column II and select the correct option given below:
| Column I | Column II | ||
| a. | Tricuspid valve | 1 | Between left atrium and left ventricle |
| b. | Bicuspid valve | 2 | Between right ventricle and pulmonary artery |
| c. | Semilunar valve | 3 | Between right atrium and right ventricle |
The correct option is B A−3,B−1,C−2
a) The primary function of the heart valves is to ensure the unidirectional flow of blood from the atria to the ventricles or from the ventricles to the aorta or pulmonary trunk. The tricuspid valve is present between the right atrium and the right ventricle. It prevents the backflow of blood from the right ventricle into the right atrium.
b) Bicuspid valve is present between the left atrium and left ventricle. It prevents the backflow of blood from the left ventricle into the left atrium.
c) The semilunar valves are present between the right ventricle and pulmonary artery and between the left ventricle and the aorta.
Thus, the correct answer is option B.
