osmosis

A

movement of water down
-low to high
semipermeable membrane

107
Q

osmotic pressure

A

amount of pressure required to stop osmotic flow of water- the higher, the stronger

108
Q

osmolarity

A

measures the total milliosmoles/L of solution

109
Q

osmolality

A

measures the number of milliosmoles/kg of water

hypotonic

A

solutions that are less concentrated than in the cells

Q

hypertonic

A

fluids that are more concentrated than in the cells

113
Q

hydrostatic pressure

A

the force of a fluid in a compartment pushing against a cell membrane or vessel wall

fluid is trapped where it is difficult or impossible for it to move back into cells or blood vessels

118
Q

hypothalamic-pituitary regulation of water balance

A

119
Q

renal regulation of water balance

A

-primary organs for regulating fluid and electrolyte balance
-average person absorbs 99% of kidney filtrate

120
Q

adrenal cortical regulation of water balance

A

121
Q

cardiac regulation of water balance

122
Q

GI regulation of water balance

A

-oral intake for most water
-small amount of water eliminated from feces
-vomiting and diarrhea are big water loss

123
Q

gerontologic considerations

A

kidney structure changes decrease ability to conserve water
hormonal changes and loss of sub q tissue

124
Q

fluid and electrolyte imbalances

A

-directly caused by illness or disease
