Question

Which blood cell helps individuals fight infection?

Answers

  1. Leukocytes
    • Rationale:

      White blood cells, or leukocytes, are primarily responsible for helping the body to fight infection.

  2. Platelet cells
    • Rationale:

      Platelet cells are responsible for coagulation and do not play a significant role in fighting infection.

  3. Erythrocytes
    • Rationale:

      Erythrocytes, or red blood cells (RBCs), are primarily responsible for transporting oxygen throughout the body; however, they do not play a significant role in fighting infection.

  4. Red blood cells
    • Rationale:

      Red blood cells (RBCs) is another term used to describe erythrocytes, which transport oxygen throughout the body. They do not play a significant role in fighting infection.

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

White blood cells (WBCs) are primarily responsible for fighting infection. The term that is used to describe all WBCs is leukocytes. There are five specific types of leukocytes, including: basophils, eosinophils, lymphocytes, monocytes, and neutrophils.
