Quiz 2 Flashcards
Intracellular compartment
2/3 of fluid in body
Ways fluid moves
Intracellular, interstitial, and intravascular
Extracellular compartment
Interstitial spaces, plasma, transcellular
Diffusion
Particles move from high concentration to low concentration
Osmosis
Movement of water across semipermeable membrane, water moves to higher concentration
Normal serum osmolarity is
275- 295 mOsm/kg
Hypotonic fluids
Makes cells swell, less concentration of solutes than plasma
Hypertonic fluids
Makes cells shrink, greater concentration of solutes than plasma
Isotonic fluids
No change in cell size
Capillary hydrostatic pressure
Pushes water into intravascular to interstitial
Capillary oncotic pressure
pulls fluid into intravascular by protein
