exit for urine from bladder
Filtration (glomerulus)
arteries bring blood to kidneys/filters blood at glomerulus
glomerular filtrate
Substances like plasma that filter out of the blood through the thin walls of the glomeruli
(blood not filtered)
reabsorption
glomerular filtrate enters the tubule

reabsorption occurs in ____
proximal convoluted tubule
secretion ____ removed
