  1. Question 1

    Q1. Antidiuretic hormone (ADH) is released to prevent dehydration. On which specific part of the nephron does this hormone primarily exert its effect?

    • A) Collecting ducts
    • B) Proximal tubule
    • C) Loop of Henle
    • D) Bowman's capsule

    Answer: Collecting ducts
