The diagram P and Q below show the transverse section of two blood vessels directly connecting the heart and the lungs.

Which heart chamber is connected to vessel Q?

A

Left atrium

B

Left ventricle

C

Right atrium

D

Right ventricle

Text Solution

Verified by Experts

The correct Answer is:
D
In the given figure, P is a vein because it has wide lumen, thinner wall and Q is an artery because it has narrow lumen and thicker wall. They must be pulmonary vein and pulmonary artery respectively.
Pulmonary artery (Q) emerges from right ventricle and pulmonary vein (P) is connected to left atrium.
