Document Summary

The urinary system chapters 1(cid:1012)-1(cid:1013: kidneys, main kidney functions, primarily responsible for maintaining stability of ecf volume, electrolyte composition, and osmolarity, main route for eliminating potentially toxic metabolic wastes and foreign compounds from the body. Filtrate, which will become urine, is formed in this process: tubular re-absorption. Involves the transfer of substances from tubular lumen into peritubular capillaries: highly selective and variable process. Plays tole in reabsorbing glucose, amino acids, h2o, cl-, and urea. Plays (cid:272)(cid:396)iti(cid:272)al (cid:396)ole i(cid:374) kid(cid:374)eys" a(cid:271)ility to produce urine of varying concentrations. Variable and subject to hormonal control; plays role in regulating ecf volume. As filtrate flows down, water leaves the tubule as the osmolarity of the extracellular fluid increases. Loss of water increases the osmolarity of the filtrate. At the bottom of the loop, the concentration of the filtrate and the extracellular fluid is equal (1200 mosm): ascending limb is impermeable to water, but permeable to nacl.
