Quizplus · Accepted Answer

Capillaries have thin walls that allow for the exchange of water and solutes between the plasma and interstitial fluid. Arteries, arterioles, and veins have thick walls that are designed for transport and regulation of blood flow. Alveoli are air sacs in the lungs and do not have a role in the exchange of water and solutes.
