recall that urine contains water urea and salts
two kidneys filter.
urine collects in bladder
urine contains salts and water and urea
osmoregulation
removal of urea is excretion of metabolic waste.

describe the role of ADH in regulating the water content of the blood



ADH - Anti - Diruetic - Hormone
flows through bloodstream, aimed at the kidney, specifically the collecting duct
ADH has ability to make blood more/less concentrated.

understand that selective reabsorption of glucose occurs at the proximal convelated tubule








reabsorption goes from glomerial filtrate to blood
*at end of nephron urine exits*
urine does not contain glucose.
if urine contains glucose, you have DIABETES.

2.72

understand that water is reabsorbed into the blood from the collecting duct








bowmans capsule - location of ultrafiltration
glomerula filtrate contains- glucose, water, salts, and urea
flitration filters too much water.
when filtrate reaches the 'collecting duct' the water is removed from the filtrate.
water is returned back to blood vessels
called 'sclected rehabsorptoin of water' - occurs in collecting duct.
