Question

Which process is defined as the activation and adhesion of platelets in the blood in addition to the collection of platelet clusters at the area of bleeding plus the formation of fibrin to stop active bleeding?

Answers

  1. Hemorrhage
    • Rationale:

      Hemorrhage is the medical term for active and severe bleeding.

  2. Coagulation
    • Rationale:

      Coagulation is defined as the action of a liquid (e.g., blood) changing to a solid or semi-solid state. This process occurs as a result of coagulation factors, fibrin, and platelets.

  3. Coagulopathy
    • Rationale:

      Coagulopathy is the medical term for any disorder that inhibits the body’s ability to coagulate or form clots to stop active bleeding.

  4. Hematopoiesis
    • Rationale:

      Hematopoiesis is the medical term for the production of blood cells within the body.

Overview

There are three primary types of blood cells within the body: red blood cells (RBCs), white blood cells (WBCs), and platelets.

Explanation

Learning Outcomes

Platelets play an active role in the body’s ability to stop bleeding. Low levels of platelets inhibit coagulation. Coagulation is defined as the activation and adhesion of platelets in the blood. This process not only includes the collection of platelets at the site of injury but the production of fibrin which all work together to form a plug to stop active bleeding.
