Fluid/Electrolyte Flashcards
Diffusion
Movement of substances from an area of high concentration to low concentration
Facilitated diffusion
Using carrier molecule to move from an area of high concentration to low concentration
Active Transport
Molecules move against concentration gradient
Osmosis
Water molecules move from an area of lesser concentration to an area of higher concentration
Osmolality
Expression of the total concentration of solute per kilogram of water
Isotonic
Having the same osmolality as normal plasma
Hypotonic
Having lower osmolality than normal plasma- cells swell
Hypertonic
Having higher osmolality than normal plasma- cells shrink
Hydrostatic Pressure
PUSHING force for movement of fluid
Oncotic Pressure
PULLING force for movement of fluid
First spacing
Normal distribution of fluid in the ICF & ECF
