What is the function of fibrinogen?

• A. Maintains osmotic pressure.
• B. Essential for blood clotting.
• C. Carries oxygen.
• D. Regulates immune response.

Answer: (B)

Fibrinogen’s role is in blood clotting. It is a soluble plasma protein produced by the liver that, when thromb in is activated, is cleaved to form fibrin. The resulting fibrin strands weave through the platelet plug to create a stable mesh, trapping cells and stabilizing the clot to stop bleeding. Without this conversion, a clot won’t form properly, leading to bleeding disorders. This function is distinct from maintaining osmotic pressure (albumin), carrying oxygen (hemoglobin), or regulating the immune response (other immune proteins and cells).
