Question

multiple choice question
vascular spasm, platelet plug formation, and ______ are three hemostatic mechanisms.

o infarction
o agglutination
o vasodilation
o coagulation

Explanation:

Hemostasis involves stopping bleeding. Vascular spasm constricts blood vessels, platelet plug formation creates a temporary seal, and coagulation forms a blood - clot to permanently seal the break in the vessel. Infarction is related to tissue death due to lack of blood supply, agglutination is mainly about the clumping of cells like in blood typing, and vasodilation is the widening of blood vessels which is not a hemostatic mechanism.

Answer:

D. coagulation
