Answer:
C. Platelet adhesion
Explanation:
Platelet adhesion comes first in the process of hemostasis.
The process of hemostasis has got three phases:
- Vascular spasm
- Platelet plug formation
- Blood coagulation
The process occurs in the body in the event of a bleeding injury.
In the first phase, damaged blood vessels constrict to prevent more bleeding.
In the second phase, platelets adhere to damaged endothelium to form platelet plug.
In the third phase, fibrinogen is converted to fibrin to form a clot.
