hypothermia, lethargy, and coma
thyroid crisis - ANS - also called thyrotoxicosis
- a sudden worsening of hyperthyroidism, respiratory depression,

nausea/vomiting, and secondary dehydration
- medical emergency
osmosis - ANSWER movement of water across a semi-permeable membrane
diffusion - ANSWER the movement of particles/solutes from an area of high
concentration to an area of low concentration
,hydrostatic pressure - ANSWER pushes water
osmotic forces - ANSWER pulls water; pressure needed to prevent migration
of solvent (H2O)
tonicity - ANSWER osmotic pressure of two solutions separated by a
semi-permeable membrane; decreases the concentration of particles in the
solutions
isotonic - ANSWER equal solute concentrations, causes no fluid shifts
hypotonic - ANSWER lower solute concentrations, causing fluids to shift from
intravascular to intracellular space
hypertonic - ANSWER higher solute concentrations, causing fluids to shift
out of cell to intravascular space
oncotic pressure - ANSWER the component of osmotic pressure that is due
to colloids (largely albumin); This can be called colloid osmotic pressure
active transport - ANSWER movement of a substance against a concentration
gradient; energy is required

transmission, and muscular contraction
- regulated by the parathyroid gland
- *has inverse relationship with phosphorous (phosphate)*
- *has synergistic relationship with magnesium*
