Capillaries
Capillaries are the smallest of the blood vessels, the tubes that carry blood. They connect arteries and veins.
Capillaries connect the smallest branches of arteries and veins The walls of capillaries are just one cell thick.

This exchange of molecules is not possible across the walls of other types of blood vessel.
