Which of the following blood proteins plays a pivotal role in maintaining the colloid osmotic pressure of blood plasma?

A. Fibrinogen
B. Globulin
C. Albumin✓ Correct Answer
D. Prothrombin

💡 Solution & Explanation

Albumin is synthesized by the liver and serves as the primary plasma protein responsible for exerting colloidal osmotic pressure to retain fluid within blood vessels. Proteins like fibrinogen and prothrombin function primarily in blood clotting, while globulins are involved in immunity and transport. A drop in albumin levels can lead to fluid leakage into interstitial spaces, causing edema.
