The kidneys are both protected and held in place by cushions of fat. In cases of rapid weight loss, the kidneys may drop to a lower position, possibly causing kinks in a nearby tubular organ. If this happens, urine will back up into the kidneys, severely damaging them. What organ(s) is/are most-likely kinked in this situation?
A. urethra
B. renal arteries
C. ureters
D. renal veins
E. nephrons

Clarify Question
What is the key concept addressed by the question?
· This question is asking about the tubular structure that carries urine out of the kidneys.
What type of thinking is required?
· Apply level:

What do you already know about urine flow from the kidney? What other information is related to the question?
· When urine is produced in the kidney, it flows out through the renal pelvis.
· The renal pelvis opens into the ureter, which carries urine to the bladder.
· As the bladder empties, urine is carried through the urethra out of the body.
Choose Answer
Given what you now know, what information is most likely to produce the correct answer?
· Renal arteries and veins carry blood to and from the kidney, but do not carry urine.
· Nephrons filter blood within the kidney, but do not leave the kidney.
· The urethra is a passage that is distal to the bladder. It carries urine out of the body.
· Impeded urinary flow from the kidney is most immediately caused by a blockage in the ureter.
Reflect on Process
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
· Apply level:
o Answering this question correctly depended on your ability to use the anatomy of the urinary tract in a new situation. If you got an incorrect answer, did you remember that the ureter carries urine away from the kidney, or that the renal artery and vein only move blood to and from the kidney? Did you have trouble extending the path of urine flow to determine the correct answer?
