Question

"MC: Platelets have a major role in which of the following?

a) Clot retraction

b) Free calcium availability

c) Bound calcium avaialbility

d) Factor XII activation

e) Fibrinogen conversion"

Answer 1

Platelets have a major role in blood clotting or coagulation. They are involved in the conversion of fibrinogen to fibrin, which forms a mesh that traps more platelets and erythrocytes, producing a clot.

Step-by-step explanation:

The main function of platelets is blood clotting or coagulation. Platelets have a major role in blood clotting or coagulation. They are involved in the conversion of fibrinogen to fibrin, which forms a mesh that traps more platelets and erythrocytes, producing a clot.

This is the process by which blood changes from a liquid to a gel, forming a plug in a damaged blood vessel. Platelets are involved in the conversion of fibrinogen to fibrin, which forms a mesh that traps more platelets and erythrocytes, producing a clot.
