What is oncotic pressure?

Question

Quizplus · Accepted Answer

Oncotic pressure is a force that tries to pull fluid from the interstitial and intracellular spaces. This force is created by proteins such as albumin in the plasma, which attract water molecules to themselves. This force opposes the hydrostatic pressure and helps to maintain fluid balance in the body.

Answer: C

Capillary pores are small openings in the walls of capillaries, which allow small molecules and fluids to pass through. The force that attempts to push fluid out of these pores into the interstitial and intracellular spaces is called oncotic pressure. This force is generated by the proteins in the plasma, which attract water molecules to them. The hydrostatic pressure in the capillary pushes fluid out, while the oncotic pressure opposes it.
