Large Proteins Such as Albumin Remain in Capillaries Rather Than

Question

Large proteins such as albumin remain in capillaries rather than diffusing out, resulting in the
A) loss of osmotic pressure in the capillaries.
B) development of an osmotic pressure difference across capillary walls.
C) loss of fluid from capillaries.
D) increased diffusion of CO₂.
E) increased diffusion of Hb.

Accepted Answer

Large proteins such as albumin cannot diffuse out of the capillaries and therefore create an osmotic pressure difference across capillary walls, leading to the retention of fluid within the capillaries.
