Question

Daniel has small stones that are lodged in the left renal pelvis. His doctor recommends passing them naturally. Which of the following choices describes the path that these stones must take to exit the body?

a)Distal convoluted tubule- Ureter- Bladder
b)A loop of Henle- Proximal convoluted tubule- Urethra- Bladder
c)Urethra- Bladder- Ureter
d)Ureter- Bladder- Urethra

Answer 1

d) Ureter- Bladder- Urethra

Step-by-step explanation:

The renal pelvis is located just outside the renal parenchyma, it is the place where the renal calices meet to form the ureter, a long a tubular structure that extends to reach the bladder, where urine is collected and stored to be finally excreted through the urethra, a single tubular structure that connects the bladder with the exterior.

The Loop of Henle- Proximal convoluted tubule and Distal convoluted tubule are structures located inside the renal parenchyma, at the medullary and cortical portion of the kidney, way up the renal pelvis.
