F & E Flashcards
Active transport
Movement of ions or molecules across cell membranes, usually against a pressure gradient
anion
ion that carries a negative charge
cation
Ion that carries a positive charge
colloid osmotic pressure
pressure exerted by plasma proteins on permeable membranes in the body, The “ pull” force bringing fluid back into the intravascular space
Diffusion
tendency of solutes to move freely throughout a solvent from an area of higher concentration to an area of lower concentration until equilibrium is reached
edema
accumulation of fluid in extra-cellular spaces
electrolytes
substance capable of breaking into ions and developing an electric charge when dissolved in solution
filtration
passage of fluid through a permeable membrane whose spaces do not allow certain solutes to pass
hydrostatic pressure
force exerted by a fluid against a container wall, this is the “Push” of fluid out of the intravascular space
Hypercalcemia
excess of calcium
Hyperkalemia
excess of potassium
hypermagnesemia
excess of magnesium
hypernatremia
excess of sodium
hyperphosphatemia
above normal serum concentration of inorganic phosphorous
hypertonic
having a greater concentration than the solution with which is is being compared
hypervolemia
excess of plasma
hypocalcemia
insufficient amount of calcium
hypokalemia
insufficient amount of potassium
hypomagnasemia
insufficient amount of magnesium
hyponatremia
insufficient amount of sodium
hypophosphotemia
below-normal serum concentration of inorganic phosphorous
hypotonic
having a lesser concentration than the solution with which it is being compared
hypovalemia
deficiency in blood plasma
ion
atom or molecule carrying an electric charge in solution
isotonic
having about the same concentration as the solution it is being compared with
osmolarity
concentration of particles in a solution, or a solutions pulling power
osmosis
passage of a solvent through a semipermeable membrane from an area of lesser concentration to an area of greater concentration until equilibrium is establised
solutes
substances dissolved in a solution
solvent
liquid holding a substance in a solution
