Question

________ involves a cascade of reactions leading to the conversion of fibrinogen to fibrin.

1) The platelet phase
2) Fibrinolysis
3) Vascular spasm
4) Retraction
5) Coagulation

Answer 1

Coagulation involves a cascade of reactions resulting in the transformation of fibrinogen to fibrin, forming a stable fibrin mesh that traps platelets and erythrocytes, ultimately leading to blood clot formation.

Step-by-step explanation:

The process that involves a cascade of reactions leading to the conversion of fibrinogen to fibrin is Coagulation. During hemostasis, which is the cessation of bleeding, three steps are involved:

1. Vascular spasm constricts the flow of blood.
2. A platelet plug forms to temporarily seal small openings in the vessel.
3. Coagulation then solidifies the plug via a clot to complete the repair of the vessel wall after the bleeding has stopped.

This Coagulation is a multi-step process often described as a cascade, because one event triggers the next in a sequence, leading to the production of a fibrin mesh that stabilizes the clot by trapping platelets and erythrocytes.
