Question

Which statement regarding the function of the urinary system requires additional education?

Answers

  1. “The urinary system plays a role in waste removal by stooling.”
    • Rationale:

      While the urinary system does remove waste products from the body, it does so through urination and not defecation, or stooling; therefore, this statement requires additional education.

  2. “The urinary system plays a role in the filtration of blood.”
    • Rationale:

      This statement indicates a correct understanding of the functions of the urinary system as this system plays a role in the filtration of the blood.

  3. “The urinary system helps to maintain acid-base balance.”
    • Rationale:

      This statement indicates a correct understanding of the functions of the urinary system as this system plays a role in the body’s acid-base balance.

  4. “The urinary system helps to maintain blood pressure.”
    • Rationale:

      This statement indicates a correct understanding of the functions of the urinary system as this system plays a role in maintaining blood pressure.

Overview

The urinary system (i.e., the renal system; the genitourinary system) has several different functions in the maintenance of homeostasis.

Explanation

Learning Outcomes

The primary functions of the urinary system include the following:
Eliminates waste products from the body (via the process of urination).
Regulates both blood pressure and volume and pressure.
Controls electrolyte and metabolite levels.
Regulates the pH of the blood.
When evaluating understanding of information presented, it is essential to review each statement and its accuracy. The statement that requires additional teaching regarding the functions of the urinary system is that, “The urinary system plays a role in waste removal by stooling.” This statement is incorrect; therefore, requires clarification.
