Oncotic pressure (colloid osmotic pressure) is determined by:
A) concentration of sodium.
B) plasma proteins.
C) hydrostatic pressure.
D) availability of membrane transporter proteins.

Question

Quizplus · Accepted Answer

Oncotic pressure, also known as colloid osmotic pressure, is determined by the presence of plasma proteins, particularly albumin. These proteins create a pressure gradient that helps to maintain fluid balance between the blood and surrounding tissues. The other choices listed do not directly affect oncotic pressure.
