The route of urine excretion from kidney to outside of body is:
- A
Kidney → ureter → urinary bladder → urethra
- B
Urinary bladder → kidney → ureter → urethra
- C
Kidney → urethra → urinary bladder → ureter
- D
Kidney → ureter → urethra → urinary bladder
Option A describes the correct route of urine excretion. The kidney filters blood and forms urine. This urine is to be excreted out of the body, and from the kidney, it drains into the ureter. Each kidney drains into one ureter, which is a long muscular tube, that leads into the urinary bladder, which is a sac-like organ that collects urine from the kidney. When a certain amount of urine has been collected, it is urinated out by a thin tube known as the urethra.All of the remaining options describe jumbled up/incorrect routes of urine excretion.
