Solution
Correct Answer:
Albumin
- Plasma Proteins: Blood plasma contains several important proteins.
- Albumin: It is the most abundant plasma protein produced by the liver.
- Functions: It acts as a transport protein for various substances. Its most critical role is maintaining the Colloid Osmotic Pressure (also called oncotic pressure).
- Clinical Importance: This pressure draws water from the tissues back into the capillaries, preventing edema and maintaining blood volume.
- Others: Fibrinogen and Prothrombin are for blood clotting; Immunoglobulins are antibodies for defense.
This medium difficulty biology question is from the chapter human physiology, covering the topic of blood components. It appeared in the 2025 exam.
