Which one of the following is the correct sequence of organs that occur in the path of urine flow in human body?
General KnowledgeBiology
- AKidney, ureter, urinary bladder, urethra.
- BKidney, urinary bladder, ureter, urethra.
- CKidney, ureter, urethra, urinary bladder.
- DUrinary bladder, kidney, urethra, ureter.
Explanation
Urine is formed by filtration in the kidney, carried by the ureter to the urinary bladder where it is stored, and finally expelled through the urethra. The correct order of organs in the path of urine flow is therefore option A. Urine is formed in the kidney and the ureter merely transports it to the bladder for temporary storage. The urethra is the final exit tube, so it must come after the bladder, not before. Option A is the only sequence that respects this anatomy.
