The main role of the kidneys is maintaining homeostasis. The CHD patients have showed a significa The word homeostasis derives from Greek, with home meaning similar, and stasis, meaning stable.When used as an adjective, it is homeostatic. The kidneys remove wastes. The content of uric acid in blood plasma has been determined and its relation with the homeostatic renal function has been studied in CHD and hypertensive patients. The kidney maintains acid:base homeostasis. Regulation of blood pressure A near constant. sium homeostasis. 5. excretion of wastes. This allows for maintenance of blood They also get rid of waste products, especially a nitrogen-containing compound called urea. Renal failure is the inability of the kidney to perform its functions and occurs due to Kidney function depends on an unimpeded blood supply, functioning renal parenchyma, and an unobstructed outflow of urine.

The kidney maintains the constancy of the internal environment through the excretion of urine, Urine contains excess water, electrolytes, acids, and alkalis, Moreover, it contains the waste products of metabolism, so, the kidney plays an important role in: Maintenance of water balance. 6. production of hormones. The kidneys perform the following functions: Removal of metabolic wastes. Inulin-clearance Inulin is Carbon dioxide (CO 2), when dissolved in the The kidneys function to maintain homeostasis, not disturb it. They also have other important functions that maintain homeostasis in the body The kidneys perform many crucial functions, including:maintaining overall fluid balance.regulating and filtering minerals from blood.filtering waste materials from food, medications, and toxic substances.creating hormones that help produce red blood cells, promote bone health, and regulate blood pressure. The kidneys remove waste products from metabolism such as urea, uric acid, and creatinine by producing and secreting urine. As discussed above, Guyton 17 clearly articulated the argument for the central role for the kidney in BP control, and the relationship between alterations in systemic blood pressure and changes in renal sodium excretion is well documented.

The primary function of the kidneys is to maintain a stable internal environment (homeostasis) for optimal cell and tissue metabolism. 4. homeostatic regulation of pH. Homeostasis in mammals. The renal system plays an essential homeostatic function through urine production and alterations in: Water handling. Homeostasis describes the physiological condition of a system under normal conditions. Different factors that can affect intrarenal oxygen homeostasis, including alterations Anatomy/Function of the Kidney Structure/Function 1% of body mass 25% of resting cardiac output Passes total blood volume every 4-5 minutes Filters 180 l per day and reabsorbs Homeostatic control so that cells can function independently of fluctuations in conditions of external environment.
The six general areas of kidney function: 1. regulation of extracellular fluid volume and blood pressure. The gland is situated on the anterior side of the neck, lying against and around the larynx and trachea For example, your body shivers to maintain a relatively constant body temperature when the external environment gets colder. Maintenance of electrolyte balance. The main function of kidneys, the most complex organs of the urinary system, is to sustain homeostasis for optimal cell and tissue metabolism. Homeostasis requires that amounts gained must be equal to that lost. The main job of your kidneys is to regulate the amount of water in the body and balance the concentration of mineral ions in the blood. The kidney undergoes autolysis rapidly, and kidneys from moribund animals or animals dying on test have histologic changes associated with autolysis. Their basic functions include: 1.
