Question

Correct pathway or passage of urine is

• A. Renal cortex bladder --> Medulla--> Urinary bladder--> Urethra
• B. Renal vein-->Urethra -->Bladder -->Ureter
• C. Collecting duct -->Ureter -->Bladder -->Urethra
• D. Pelvis -->Medulla -->Urinary bladder -->Urethra

Answer 1

Answer: (C)

Collecting duct -->Ureter -->Bladder -->Urethra

The urine formed in nephron is collected through collecting ducts. These collecting ducts fuse to form minor calyces which are followed by major calyces. These major calyces join the kidney pelvis. Urine flows into ureters from kidney pelvis. Then the ureter transports urine into the urinary bladder. The urethra is a long tube which connects urinary bladder to the urinary meatus for removal of urine from the body. In males, urethra travels through the penis and meet the urethral meatus located at the tip of the penis. In females, urethra connects to the urethral meatus above the vagina. The urethra is also known as the urinary opening. So the correct sequence of urine So the correct pathway or passage of urine is Collecting duct -->Ureter --> Bladder --> Urethra.

So, the correct answer is 'Collecting duct -->Ureter -->Bladder -->Urethra'.
