Blood colloid osmotic pressure is largely due to .a. the high amount of water in the blood, and it promotes filtration from arterioles. b. the pressure generated by the heart, and it favors osmosis into the arteriole end of the capillary bed. c. the proteins in the blood, and it promotes reabsorption. d. the high amount of water in the blood, and it promotes diffusion out of the capillaries. e. the proteins in the blood, and it promotes filtration.

Blood colloid osmotic pressure is largely due to the proteins in the blood, and it promotes reabsorption.

Blood colloid pressure is the osmotic pressure exerted by plasma proteins (because its concentration in plasma is about three times higher than that in interstitial fluid).

Therefore, we can conclude that blood colloid pressure can be called colloid osmotic pressure, referring to the process and the solutes involved.

Option C,   the proteins in the blood, and it promotes re-absorption.

Explanation:

The colloidal proteins concentration within the blood creates a pressure known as blood colloidal osmotic pressure which  restrains the movement of suspended blood proteins outside the cell membrane due to which the concentration of protein with in the blood increase and in order to lower this concentration water is absorbed by the semipermeable layer of capillary cell. Hence, it can be said that it attracts water.

Hence, option C is correct

i think that the best answer would be c.

tell me if im wrong : )

the answer is b. glad to .
