What is the opening that allows urine to exit the body?

• A. Glomerulus
• B. Meatus
• C. Renal pelvis
• D. Cortex

Answer: (B)

The opening that allows urine to exit the body is the urinary meatus, the external opening of the urethra. Urine is produced in the kidneys and collected in the renal pelvis, travels down the ureter to the bladder, and is expelled outside through the urethra. The glomerulus is part of the filtration unit inside the kidney, not an exit to the outside. The renal pelvis collects urine inside the kidney before it enters the ureter, and the cortex is the outer tissue layer of the kidney. Only the urinary meatus serves as the external exit for urine.
