Which organ in the urinary system is a hollow muscular tube that allows for the passage of
urine from the bladder to the urinary meatus?
Response
Feedback:
The correct answer is urethra. The urethra attaches to the bottom of the
bladder and extends to the urinary meatus (opening to the outside of the body.)
The urethra is smaller in females and larger in males. The other answers are
incorrect because the ureter is a tube that allows passage of urine from the
kidneys to the bladder. The kidneys filter the blood and form urine. The bladder
is a muscular sac that acts as a temporary storage for urine.
