Exchange Between a Blood Vessel and the Cells That Surround

Question

Exchange between a blood vessel and the cells that surround it can occur only in
A) arteries.
B) arterioles.
C) veins.
D) venules.
E) capillaries.

Accepted Answer

Exchange between a blood vessel and the cells that surround it occurs only in capillaries. Capillaries are small, thin-walled blood vessels that allow for the exchange of gases, nutrients, and waste products between the blood and surrounding cells. Arteries, arterioles, veins, and venules do not have the same level of permeability for exchange as capillaries.
