Blood pressure in the pulmonary artery is

A

more than that in the carotid

B

more than that in the pulmonary vein

C

less than that in the vena cava

D

same as that in the aorta

Text Solution

Verified by Experts

The correct Answer is:
B
Blood pressure in different blood vessels
Artery `gt` Arteriole `gt` Capillary `gt` Venule `gt` Vein (vena cava). The pulmonary arteries have thicker smooth muscles and connective tissues than the pulmonary veins to accommodate the higher pressure and speed of blood.
