Urine is the fluid that is formed in the uriniferous tubules of the kidney.. From here, it goes to the renal pelvis to the ureter.
ureter's function is to transport urine from the kidney to the urinary bladder as it has a mucosa layer that performs peristalsis.
the urine, on reaching the bladder moves out from our body or is excreted via the urethra. the urinary bladder has an epithelial layer of tissue that is able to stretch so as to store a large amount of urine.
