Question

Which body system organ is primarily responsible for the production of erythrocytes?

Answers

  1. Heart
    • Rationale:

      The heart is the pump which helps to circulate blood throughout the body. This organ, however, is not primarily responsible for the production of erythrocytes.

  2. Spleen
    • Rationale:

      While the spleen does produce some blood cells, it is primarily responsible for the storage of erythrocytes.

  3. Lymph nodes
    • Rationale:

      The primary function of lymph nodes is the filtering of lymph to both fight and identify infection.

  4. Bone marrow
    • Rationale:

      The bone marrow is the body system organ that is primarily responsible for the production of RBCs, or erythrocytes.

Overview

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

Explanation

Learning Outcomes

Hematopoiesis is the medical term for the production of blood cells. Erythrocytes, or RBCS, are primarily produced by the bone marrow. While some erythrocytes are produced in the spleen this organ is primarily responsible for storage.

Test Taking Tip

Consider the structure and function of each organ to correctly answer this question.
