MEDICAL PHYSIOLOGY

Detailed explanation-1: -1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade.

Detailed explanation-2: -Hemostasis may be categorized into primary (platelet plug formation), secondary (formation of a stabilized fibrin clot through the coagulation cascade), and tertiary (formation of plasmin for breakdown of fibrin via fibrinolysis) concurrent processes.

Detailed explanation-3: -Hemostasis is the physiological process by which bleeding ceases. Hemostasis involves three basic steps: vascular spasm, the formation of a platelet plug, and coagulation, in which clotting factors promote the formation of a fibrin clot.

Detailed explanation-4: -Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.
