Question

multiple choice question
once the tubular fluid leaves the ______, it is called urine.
o pct
o collecting duct

Explanation:

The collecting duct is the final part of the nephron where the tubular fluid undergoes final adjustments. Once it leaves the collecting duct, the fluid is called urine. PCT (Proximal Convoluted Tubule) and DCT (Distal Convoluted Tubule) are earlier parts of the nephron where reabsorption and secretion occur, but the fluid is still not yet urine at those stages.

Answer:

collecting duct
