Q1. Where is urine stored before it is released from the human body?
- (a) In the kidneys
- (b) In the ureters
- (c) In the urinary bladder
- (d) In the urethra
Answer & solution
Answer: (c) In the urinary bladder
Correct Answer: 3 – In the urinary bladder.
After urine is produced in the kidneys, it travels through the ureters to the urinary bladder, where it is stored before being expelled from the body through the urethra. The urinary bladder is a muscular, hollow organ that can hold approximately 400–600 ml of urine.
The kidneys (Option 1) produce urine but do not store it.
The ureters (Option 2) are tubes that transport urine from the kidneys to the bladder.
The urethra (Option 4) is the tube through which urine is expelled from the body, not stored.
