what percentage of body weight is composed of fluids
60%
what regulates fluid balance and nerve and muscle transmission
electrolytes
hydrostatic pressure
pressure excerted on walls of the blood vessels
osmotic pressure
pressure excerted by the protein in the plasma
high osmolality =
dehydration
low osmolality=
water excess
diffusion
solutes move from an area of high concentration to low
2 areas where filtration is important
kidneys and liver
Filter kidneys skin lungs GI
Filter kidneys: 1500-2000 skin:600 lungs: 400 GI: 100-200
Total Fluid Loss=
Total fluid loss 2600 per day=total fluid gain 2600 per day
Biggest indicator of fluid volume excess is
weight put them on the scale

1 liter of water fluid = lbs
2.2 pounds
