Hormones are important signaling
molecules controlling the kidneys in the regulatory
processes of osmoregulation and excretion.
Osmoregulation keeps
body fluids from becoming too diluted or too concentrated.
Excretion is the process
of ridding the body of excess metabolic wastes,
including water.
Four major hormones help to
maintain homeostasis by regulating the concentration
and amount of urine excreted. They are:
1) Antidiuretic hormone
(ADH)
2) Aldosterone
3) Angiotensin II
4) Atrial natriuretic peptide (ANP)
