Paired organ important in homeostasis.
The kidneys have significant biological reserve. By the time the serum creatinine rises - usually the first sign of renal impairment, the kidneys have lost a high proportion (e.g. 75-90%) of their physiological function.
(see Renal physiology)
- Involved in regulation of body water, pH, calcium, sodium, potassium
- Excretes waste products (e.g. urea)
- Controls blood pressure (via Renin-Angiotensin-Aldosterone system)
- Drives erythropoesis (through production of erythropoeitin)
