The kidney is an important homeostatic organ involved in the control of salts and water in the body. Homeostasis requires that amounts gained must be equal to that lost. The word homeostasis derives from Greek, with home meaning similar, and stasis, meaning stable.When used as an adjective, it is homeostatic.

Ion concentration-need proper amounts of Na+, Cl-, K+, and Ca2+: nervous, cardiac& muscle function-imbalances The kidneys are essential for cleansing the blood and eliminating urine waste from the body. The attenuation of renal filtration processes has been revealed in a half of the 117 patients. Renal failure is the inability of the kidney to perform its functions and occurs due to In the immune system, homeostasis therefore refers to its function and maintenance in the uninfected host 6.

Homeostasis Definition. Regulation of water balance: Kidneys secrete excess hypotonic urine if the body has excess water and hypertonic urine if the body has deficiency of water. The lungs and kidneys work together to produce a normal extracellular fluid and arterial pH of 7.35-7.45 (34-46 nmol.l-1 H+ concentration). Nitric oxide (NO) is an important molecular mediator of numerous physiological processes in virtually every organ. The kidney is central to water, electrolyte, acidbase and calcium homeostasis, as well as having a crucial role in regulation of blood pressure, and via the action of erythropoietin, manufacture of red blood cells. Estimation of characteristic parameters of the kidney. The main function of kidneys, the most complex organs of the urinary system, is to sustain homeostasis for optimal cell and tissue metabolism. An important function of the kidneys is to produce urine and disturb homeostasis The urinary system excretes water, salt, urea, drugs and other substances from the human body in urine, which is eliminated 4. For example, your body shivers to maintain a relatively constant body temperature when the external environment gets colder.

Regulation of blood pressure Homeostasis is an organisms process of maintaining a stable internal environment suitable for sustaining life. Total-body potassium (K+) content and appropriate distribution of K+ across the cell membrane is vitally important for normal cellular function. The renal system plays an essential homeostatic function through urine production and alterations in: Water handling. The kidney secretes hormones, including erythropoietin in response to hypoxia, renin in Homeostasis refers to the maintenance of relatively constant internal conditions. The renal arteries provide the kidneys with blood, which then leaves through the renal vein.
