Question

What is the relationship between the renal tubule and the peritubular capillaries in the outer kidney?

1) The renal tubule and the peritubular capillaries are not connected.
2) The renal tubule filters waste products from the blood into the peritubular capillaries.
3) The peritubular capillaries transport filtered substances from the renal tubule back into the bloodstream.
4) The renal tubule and the peritubular capillaries exchange oxygen and carbon dioxide.

Answer 1

The renal tubule and the peritubular capillaries are closely connected in the outer kidney. After the blood is filtered in the glomerulus, the filtered substances pass into the renal tubule. Then, the peritubular capillaries, which surround and interact with the renal tubule, transport the filtered substances back into the bloodstream.

Step-by-step explanation:

The renal tubule and the peritubular capillaries are closely connected in the outer kidney. After the blood is filtered in the glomerulus, the filtered substances pass into the renal tubule. Then, the peritubular capillaries, which surround and interact with the renal tubule, transport the filtered substances back into the bloodstream.
