What receives urine from the ureters and stores urinary volume?

• A. Ureter
• B. Renal cortex
• C. Renal pelvis
• D. Urinary bladder

Answer: (D)

The urinary bladder is the structure that receives urine from the ureters and stores it until voiding. Urine forms in the kidneys, moves into the renal pelvis, travels down the ureters, and then collects in the bladder. The bladder is a distensible sac with a muscular wall (detrusor) and transitional epithelium that allows it to expand as it fills and contract to expel urine through the urethra. The other options don’t store urine: the ureter transports urine from kidney to bladder; the renal cortex is involved in filtration within the kidney; the renal pelvis is the kidney’s internal collecting area just before the ureter, not a body-wide storage organ.
