1) The large amount of blood, under relatively high pressure, that flows through kidney glomerulae whose capillaries have large pores - This is the correct answer.
A considerable amount of the blood plasma filters through the glomerulus into the nephron tubule. This results from the large amount of blood flow through the glomerulus, the large pores (40 Angstrom [Å]) in the glomerular capillaries, and the hydrostatic pressure of the blood.
2) The proximal tubule of the nephron - This is the correct answer.
Secretion occurs in the proximal tubule section of the nephron and is responsible for the transport of certain molecules out of the blood and into the urine.
3) Polarity - This is the correct answer.
The ultimate fate of a substance filtered into the renal tubule is governed by its polarity. Those substances that are ionized remain in the urine and leave the body.
