true
True or false: the tiny filtering structures of the kidneys are called nephrons
True
True or false: the region of the renal tubule closest to the glomerular capsule is the distal convoluted tubule.
false
True or false: blood protein and blood cells are too large to pass through the filtration membrane and should not be found in filtrate
true
True or false: most reabsorbtion occurs in the proximal convoluted tubule of the nephron
true
True or false: the pigment that gives urine its characteristic yellow color is urochrome
