Water, Major minerals, and trace minerals Flashcards
fluids in a cell
intracellular fluids
fluids outside of cells
extracellular fluids
extra cellular fluids that surround each cell
interstitial fluids
extracellular fluids in blood vessels
intravascular fluids
thirst is sensed by…
mouth, hypothalamus, nerves
when too much water is lost from the body and not replaced
dehydration
too much water that dilute solute concentration in the blood
hyponatremia
help maintain healthy kidneys and prevent kidney stones from forming
adequate intake of fluids
water that has high concentration of calcium and magnesium
hard water
water that has high concentration of sodium and potassium
soft water
instructions on whether to release or retain substances or water come from
ADH, renin, angiotensin, and aldosterone
blood volume or blood pressure is too low or the extra cellular fluid is too concentrated. the pituitary gland releases this hormone that that makes the kidneys reabsorb water
antiduretic hormone (ADH)
cells release this enzyme which causes the kidneys to reabsorb sodium
renin
protein in the liver, hydrolized by renin, that help in raising blood pressure by vasoconstriction
angiotensin
hormone from adrenal gland that signals the kidneys to excrete potassium and retain sodium
aldosterone
