intracellular fluid (icf)
70% of water in body, within cells
extracellular fluid (ecf)
30% of body water, outside cells
dehydration
loss of water from body/tissues
electrolytes
minerals in your body that carry electric charge
solvent
a liquid substance capable of dissolving other substances
solute
the dissolved matter in a solution; the component of a solution that changes its state
osmosis
solvent passes from area of LOW concentration to HIGH concentration
osmolarity
concentration of particles in a solution (it's pulling power)
isotonic
taking place with normal concentration(muscle), solution that contains the same concentration of water and solutes as the intracellular fluid
hypertonic solution
greater osmolarity than plasma (fluid with higher concentration)
hypotonic solution
less osmolarity than plasma (fluid w lower concentration)
Diffusion
movement of particles from HIGHER concentration to LOWER concentration
