Question

What is the final route of urine from the collecting duct to outside the body?

a) Renal pelvis, ureter, bladder, urethra
b) Minor calyx, renal pelvis, ureter, outside the body
c) Renal papilla, major calyx, bladder, urethra
d) Loop of Henle, major calyx, ureter, outside the body.

Answer 1

The correct final route for urine is from the renal pelvis through the ureter into the bladder, then through the urethra and outside the body.

Step-by-step explanation:

The final route of urine from the collecting duct to the outside of the body is as follows: urine exits the largest collecting ducts through the renal papillae, enters the minor calyces, and drains into the renal pelvis. From the renal pelvis, urine travels down the ureter to the urinary bladder, where it is stored until it is ready to be excreted. When urination occurs, urine passes from the bladder into the urethra and is finally expelled from the body. Therefore, the correct answer to the question would be 'Renal pelvis, ureter, bladder, urethra' which corresponds to selection (a).
