Question

Which system does the renal system work in conjunction in the production of red blood cells (RBCs)?

Answers

  1. Endocrine
    • Rationale:

      Endocrine glands are responsible for the secretion of erythropoietin, a hormone that is vital for the production of RBCs. The renal system assists in the production of this same hormone by activating vitamin D which also produces this same hormone.

  2. Circulatory
    • Rationale:

      The circulatory system does not work with the renal system in the production of RBCs. The circulatory system is the portal through which blood is transported throughout the body.

  3. Reproductive
    • Rationale:

      While the reproductive and the renal systems have several structures in common, they do not work together to produce RBCs.

  4. Gastrointestinal
    • Rationale:

      While the gastrointestinal and renal systems are close in proximity, they do not work together to produce RBCs.

Overview

One important function of the renal system is the production of RBCs.

Explanation

Learning Outcomes

The renal system works with the endocrine system in the production of RBCs. The renal system activates vitamin D, which not only helps to maintain strong bones, but also produces erythropoietin. Erythropoietin is an endocrine hormone that is vital for the production of RBCs.

Test Taking Tip

Consider the function of each system to determine the correct choice for this question.
