Whereas diffusion is more important for solute exchange between plasma and interstitial fluid, bulk flow is more important for regulation of the relative volumes of blood and interstitial fluid.1. True2. False

The correct answer is - option 1. true.

Explanation:

Diffusion is the process where the solute moves from higher concentration area to the low concentration area. The major example of the diffusion is in the solute exchange between plasma and interstitial fluid. Blood plasma contains water, waste contents, ions, and various nutrients. It can be transported to the interstitial fluid from blood plasma in capillaries and back.

Bulk flow is the simple protein or any other large molecule transport or movement from the blood to interstitial fluid or interstitial to blood. this is essential for regulation of the relative volumes of blood and interstitial fluid.

Thus, the correct answer is - option 1.
