Question

Which statement indicates a need for additional education regarding the function of the renal system?

Answers

  1. “Ultrafiltrate becomes urine once reabsorption and secretion occur.”
    • Rationale:

      This statement indicates a correct understanding of the renal system as ultrafiltrate becomes urine once reabsorption and secretion both occur.

  2. “Secretion is a term that is used synonymously with reabsorption.”
    • Rationale:

      This statement requires additional teaching as secretion is the opposite of reabsorption.

  3. “Reabsorption occurs after ultrafiltrate is produced but before urination occurs.”
    • Rationale:

      This statement indicates a correct understanding of the renal system as reabsorption occurs after ultrafiltrate is produced but before urination occurs.

  4. “The filtration process includes removing protein from the blood to make ultrafiltrate.”
    • Rationale:

      This statement indicates a correct understanding of the renal system as the filtration process includes removing protein from the blood to make ultrafiltrate

Overview

The renal system has several different functions in the maintenance of homeostasis within the human body.

Explanation

Learning Outcomes

The three primary functions of the renal system include filtration, reabsorption, and secretion. Secretion entails the movement of molecules and waste products into the urine from the blood after processing by the kidney. Secretion is the opposite of reabsorption; therefore, the statement “Secretion is a term that is used synonymously with reabsorption.” requires additional education.

Test Taking Tip

Read each statement and ask yourself if it is true or false. The false statement is the correct choice for this question.
