What are the Most Abundant Plasma Proteins That Also Establish

Question

What are the most abundant plasma proteins that also establish the osmotic pressure of the plasma?
A) fibrinogens
B) gamma globulins
C) astrocytes
D) albumins
E) hemoglobin

Accepted Answer

Albumins are the most abundant plasma protein, and they also establish the osmotic pressure of the plasma by drawing water into the blood vessels. The other proteins listed (fibrinogens, gamma globulins, and hemoglobin) are less abundant and/or do not play a significant role in establishing osmotic pressure. Astrocytes are not a plasma protein at all, but rather a type of cell found in the nervous system.
