Sam Farley · Answer 1

C) exchange of dissolved gases between the blood and the interstitial fluid.

Explanation:

It's not A because that's the definition of external respiration.

It's not B because that's the definition of homeostasis.

It's not D because that binding is all part of the homeostasis.

It's not E because that's part of the metabolism of each tissue.

The right answer is C because the definition of internal respiration is the exchange of oxygen and carbon dioxide between blood and tissue through the interstitial fluid.
