Hemostasis is dependent upon which of the following?

Question

Quizplus · Accepted Answer

Hemostasis involves the interaction between platelets, coagulation proteins, and blood vessels to stop bleeding. Platelets form a plug at the site of injury, and coagulation proteins lead to the formation of fibrin, which stabilizes the plug. Blood vessels also play a role in hemostasis by constricting to limit blood flow to the injured area.

Answer: A
 Hemostasis also requires a delicate balance between coagulation and fibrinolysis inhibitors, which prevent blood clots from forming in healthy blood vessels. These inhibitors include antithrombin III, protein C, and protein S.

Answer: E
 While platelets, coagulation proteins, and inhibitors play a key role in hemostasis, other factors also contribute. The rate of platelet destruction can affect the ability of the body to form a clot, and endothelial cell turnover is important for maintaining the integrity of blood vessels.
