Question

Which blood substance is needed to prevent hemorrhage?

Answers

  1. Albumin
    • Rationale:

      Albumin is defined as a simple form of protein that is soluble in water and coagulable by heat within blood serum; however, it does not play a large role in the coagulation process to prevent hemorrhage.

  2. Erythrocytes
    • Rationale:

      Erythrocytes are RBCs. Their primary function is to transport oxygen throughout the circulatory system for distribution, not in the coagulation process to prevent hemorrhage.

  3. Clotting factors
    • Rationale:

      Clotting factors, which are found in platelets, are the blood component that is responsible for coagulation which is needed to prevent hemorrhage. .

  4. White blood cells
    • Rationale:

      WBCs, or leukocytes, play a role in preventing infection; however, they do not play a role in the coagulation process to prevent hemorrhage.

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

Clotting factors, located within platelets, are the blood substance that is needed to prevent hemorrhage. Another term for clotting factors is coagulation factors. These are defined as proteins within the blood that help prevent hemorrhage.
