Which tube connects the kidney to the urinary bladder?

• A. Cortex
• B. Renal capsule
• C. Meatus
• D. Ureter

Answer: (D)

The tube that connects the kidney to the urinary bladder is the ureter. It is a muscular, peristaltic conduit that starts at the renal pelvis near the kidney and descends to the posterior wall of the bladder, delivering urine through coordinated waves. The other terms refer to parts of the kidney or unrelated openings: the cortex is the kidney’s outer tissue, the renal capsule is its protective covering, and a meatus is an opening (such as the urethral opening), not a tube between the kidney and bladder.
