If 125 milliliters of material is captured per
minute in the glomerular (Bowman's) cap-
sules, why is only 1 milliliter of urine gener-
ated each minute?
a. The renal pelvis siphons off most of it.
b. A series of tubules allow most of it to be
reabsorbed into the bloodstream.
c. The material is highly concentrated by
the time it becomes urine.
d. Hydrostatic pressure forces most of the
material back out again.
