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 hemoglobin

Question

Quizplus · Accepted Answer

Large proteins such as albumin are not able to easily pass through capillary walls and therefore remain within the blood vessels. This results in the development of an osmotic pressure difference across the walls of the capillaries, as the presence of these large molecules within the blood creates a higher solute concentration within the vessel. This difference in osmotic pressure helps to drive the movement of fluids and small molecules (such as nutrients and waste products) across the capillary walls, allowing for the exchange of materials between the blood and the surrounding tissues.
