Document Summary

Ecf (1/3) = extracellular fluid of two compartments vascular (1/3) and interstitial (2/3) Liters (2/3:1/3 relationship); 2 liters in interstial space, and 1 l would go to the vascular space; it equilibrates with interstial/vascular compartments. Normal na is 135-140 range, times that by 2 that 280. For glucose, normal is 100 divide that by 18, let"s say it"s roughly 5, so that"s not contributing much. Bun: located in the liver, part of the cycle is in the cytosol and part of it is in mitochondria. The urea comes from ammonia, that"s ammonia is gotten rid of, by urea. B/c the end product of the urea cycle is urea. The normal is about 12; divide that by 3, so we have 4. Therefore, in a normal person na is controlling the plasma osmolality. To measure serum osmolality: double the serum na and add 10. B/c na and glucose are limited to the.
