OSMOREGULATION (blood/water content) - Coggle Diagram
OSMOREGULATION (blood/water content)
high water content in blood
pituatary gland releases less ADH
high urine output, dilute
low volume of water reabsorbed by kidney
water gains, drinking, eating, metabolism
hyponatremia, too much too fast, water intoxication
nausea, confusion, less relfexes, stupor, coma
over hydration, loss of sodium from sweat
drink electrolytes to recover sodium lost from sweat
overhydration
water moves into body cells by osmosis, low to high concentration, too high = burst
low water content in blood
pituartary gland releases ADh
low urine output, concentrated
high volume of water reabsorbed by kidneys
water losses, urnination, feces, skin, breathing, eating salty foods
dehydration
caused by
sweating, excersise and hot environmnets to cool body
respiration, exhaling water vapour
water moves out of cells into blood cells shrink
water=physiological function+health
can only survive 100hrs without
body water content varies, age, sex
water = around 60%
by product of cellular respiration
metabolic water
slows dehydration but not enough to cover sweat loss
KIDNEYS
losing electrolytes through sweat signals kidneys to adjust fluid/salt balance.
water content in out blood is controlled
works with brain to maintain blood/water content by controling how much water/salts are reabsorbed or loss as urine
