Document Summary
Module #11 renal system, water & electrolyte balance (sections 11. 1 to. By the end of this section, you should be able to: describe homeostasis as it applies to body fluids and osmolarity. Homeostasis is about maintaining the internal environment and relatively stable conditions regardless of what is happening in the external environment. The kidneys are used to maintain homeostasis by regulating water balance, chemical concentrations and the ph of the blood. Filtration: movement of fluid through the glomerular capillary due to hydrostatic pressures. Reabsorption: movement of a substance from the lumen of the nephron back to the blood. Secretion: movement of a substance from the blood into the lumen of the nephron. Excretion: removal of a substance from the body: describe and distinguish between renal blood flow and renal plasma flow and give values for each. The renal blood flow is the volume of blood reaching the kidneys per unit time.
