Question

mechanism of blood clotting?​

Answer 1

Answer

The mechanism of blood clotting involves activation, adhesion and aggregation of platelets, as well as deposition and maturation of fibrin.

Answer 2

Answer:

A platelet plug is formed, and the external bleeding stops. Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.

three steps that occur in a rapid sequence:

(1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels;

(2) formation of a platelet plug; and

(3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.
