Vascular spasm, platelet plug formation, and ______ are three hemostatic mechanisms.Multiple choice question.infarctioncoagulationagglutinationvasodilation

Break Down the Problem

1. Identify the hemostatic mechanisms listed in the question: vascular spasm and platelet plug formation.
2. Determine which of the options provided completes the list of hemostatic mechanisms.

Relevant Concepts

• Hemostasis is the process that prevents and stops bleeding, involving three primary mechanisms:
  1. Vascular spasm: Immediate constriction of blood vessels to reduce blood loss.
  2. Platelet plug formation: Aggregation of platelets at the site of injury.
  3. Coagulation: The process of blood clotting.

Analysis and Detail

• The options presented are:
  1. infarction: This refers to tissue death due to lack of blood supply, not a hemostatic mechanism.
  2. coagulation: This refers to the process of clot formation, which is a key component of hemostasis.
  3. agglutination: This refers to the clumping of particles, not specifically a hemostatic mechanism.
  4. vasodilation: This is the widening of blood vessels, which is the opposite of vascular spasm.

Verify and Summarize

• The most appropriate term that completes the hemostatic mechanisms alongside vascular spasm and platelet plug formation is coagulation, as it directly relates to the blood clotting process.

Final Answer

coagulation
