Question

Quizplus · Accepted Answer

The colloid osmotic pressure or oncotic pressure is primarily due to the proteins in solution, particularly in the blood plasma, which are too large to pass through the semipermeable membrane of the blood vessel walls. This pressure helps in maintaining the fluid balance between the blood vessels and the surrounding tissues by drawing water into the circulatory system.
