THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra.

Detailed explanation-2: -As urine passes through the ureter, it does not passively drain into the bladder but rather is propelled by waves of peristalsis. As the ureters enter the pelvis, they pass laterally, hugging the pelvic walls. As they approach the bladder, they turn medially and join with the bladder wall obliquely.

Detailed explanation-3: -The ureter transports urine from kidney to the urinary bladder and urethra transports urine from the urinary bladder to outside. Blood reaches the kidney through renal artery and the filtered blood is pumped back through renal vein.
