The major and minor calyces drain into which structure?

The major and minor calyces drain into which structure?

• A. Renal pelvis
• B. Ureter
• C. Bladder
• D. Urethra

Answer: (A)

Urine is collected from the nephrons into the tiny calyces, which merge into larger calyces and then into a single central reservoir inside the kidney called the renal pelvis. The renal pelvis acts as the funnel that channels urine into the ureter, which carries it to the bladder. So the structure that the major and minor calyces drain into is the renal pelvis. The bladder and urethra are downstream pathways, and the ureter is the next step after the renal pelvis, not the immediate drainage site for the calyces.
