The muscular tube through which stored urine is passed out of the body is called –
(a) kidney
(b) ureter
(c) urethra
(d) urinary bladder
The answer is (c) urethra
Explanation:
Waste which is present in the blood has to be removed from the body. This is done by the blood capillaries in the kidneys. The wastes dissolved in water are removed as urine. From the kidneys, the urine goes into the urinary bladder through tube-like ureters. It is stored in the bladder and is passed out through the urinary opening at the end of a muscular tube called the urethra . The kidneys, ureters, bladder and urethra form the excretory system.
