  1. Question 1

    Q1. After consuming a large volume of water, a person produces dilute urine. Which hormone's secretion is suppressed to allow this homeostatic adjustment?

    • A) Antidiuretic hormone
    • B) Aldosterone
    • C) Oxytocin
    • D) Atrial natriuretic peptide

    Answer: Antidiuretic hormone

    Explanation: Low ADH reduces water reabsorption in collecting ducts; Aldosterone fails because it primarily regulates sodium and potassium balance, not pure water.
