The extracellular solutions of your body include the plasma ( extracellular solution surrounding the blood cells) and the interstitial fluid (extracellular solution surrounding the tissue cells). Edema is tissue swelling that occurs when a high level of fluid accumulates in the tissues. Although there are many causes of edema, one way that edema can occur is due increased protein concentration in the interstitial fluid of the tissues during inflammation or thyroid disease. Why would this situation result in edema?

Match the vessel characteristic on the left with the appropriatevessel type on the right (each vessel type will be used more thanonce, only 1 BEST answer for each characteristic).

Substance exchange with the tissues takes place in thesevessels

These vessels are the main site of vascular resistance

Active hyperemia directly affects the diameter of thesevessels
