REGULATION OF URINE CONCENTRATION AND VOLUME

Question 1

Three major hormonal mechanisms are involved in regulating urine concentration and volume:

Answer 1

(1) the renin-angiotensin-aldosterone mechanism,
(2) the antidiuretic hormone (ADH) mechanism, and
(3) the atrial natriuretic hormone (ANH; atrial natriuretic peptide, ANP) mechanism.
