Question

From the collecting ducts of the nephrons, urine drains directly into the

o renal pelvis.
o urinary bladder
o minor calyces.
o major calyces.
o ureter.

Answer 1

Urine produced in the nephrons drains from the collecting ducts into the minor calyces, then into the major calyces, the renal pelvis, and finally into the ureter.

Step-by-step explanation:

Urine is produced by the nephrons in the kidney and goes through a series of structures before it is excreted from the body. After urine is concentrated in the collecting ducts, it passes into renal papillae and then empties into the minor calyces. These minor calyces join to form the major calyces, which in turn drain into a large funnel-shaped cavity called the renal pelvis.

From the renal pelvis, urine flows into the ureter, which carries it to the urinary bladder. The answer to the student's question is that from the collecting ducts of the nephrons, urine drains directly into the minor calyces, then into the major calyces, followed by the renal pelvis, and eventually into the ureter.
