A person sweats heavily on a hot day. What is the response of the body to the fall in the water potential of the blood?

Answer and explanation

Correct answer: B. More ADH is released, the collecting ducts become more permeable, and a small volume of concentrated urine is produced

  1. Step 1: Osmoreceptors detect the low water potential. Step 2. ADH increases permeability, so more water is reabsorbed. Answer: more ADH and concentrated urine. Why not the others: these mismatch the hormone and the response.
