Question

Which duct takes the urine out from the urinary bladder to the outside of the body?

Answer 1

Solution:

Excretory system is composed of several urinary tracts that are used for purification of blood and expelling the excretory materials out of the body.

From urinary bladder, urine is expelled out of the humans through tube like structure called urethra.

Urethra works as per the nervous response which causes stimulation and opens the urethral opening.

Answer 2

Urine comes out of the body through a duct called urethra, which comes out of the urinary bladder.

When the brain signals the urinary bladder to release the urine, the bladder muscles squeeze to pass the urine to the urethra.

At the same time, the sphincter muscles at the juncture of bladder and the urethra are directed by brain to open up, thus allowing the free passage of urine out of the body.
