ANATOMY

Detailed explanation-1: -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. Fibrinolysis is the process in which a clot is degraded in a healing vessel. Anticoagulants are substances that oppose coagulation.

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

Detailed explanation-3: -The second critical step in hemostasis, which follows vasoconstriction, is platelet plug formation. The three steps to platelet plug formation are platelet adherence, activation, and aggregation.

Detailed explanation-4: -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.
