Question

Which of the following structures is considered "plumbing"?
A) Collecting duct
B) Ureter
C) Glomerulus
D) Two of the above are true.

Accepted Answer

The ureter is considered part of the plumbing system because it serves to transport urine from the kidneys to the bladder. The collecting duct and glomerulus are involved in urine formation and filtration, respectively, but they are not directly involved in the transport of urine out of the body.
