Question

The colloid osmotic pressure is best defined as the

a. pressure generated by the contraction of skeletal muscles pushing on the blood vessels.
b. osmotic pressure exerted by plasma proteins in the blood vessels.
c. pressure generated by the contraction of smooth muscles around the blood vessels.
d. pressure difference between the osmotic pressure of the blood plasma and the osmotic pressure of the capsular fluid.

Answer 1

The colloid osmotic pressure is defined as the osmotic pressure exerted by plasma proteins in the blood vessels, specifically the plasma proteins, that creates the colloid osmotic pressure.

Step-by-step explanation:

The colloid osmotic pressure is best defined as the osmotic pressure exerted by plasma proteins in the blood vessels.

Solutes in the blood and tissue fluid move according to their concentration gradients, but overall, the concentrations should be similar and not have a significant impact on osmosis.

It is the concentration of colloidal proteins in the blood, specifically the plasma proteins, that creates the colloid osmotic pressure.
