Match the information of Column-I with Column-II as per below :
| Column-I | Column-II |
|---|---|
| 1. Right Atrium | a. Pump oxygenated blood to body |
| 2. Left ventricle | b. Receive deoxygenated blood |
| 3. Pulmonary valve | c. Carries deoxygenated blood to lungs |
| 4. Pulmonary artery | d. Prevent backflow into right ventricle |
Choose the most appropriate option from below :
Answer: B
The correct matching is 1-b, 2-a, 3-d, 4-c.
The right atrium receives deoxygenated blood from the body through the venae cavae (1-b). The left ventricle pumps oxygenated blood to the body through the aorta (2-a). The pulmonary valve prevents backflow into the right ventricle (3-d). The pulmonary artery carries deoxygenated blood to the lungs (4-c).
The other options misplace these functions; for example, 1-a would have the right atrium pumping oxygenated blood to the body.
