PATHOLOGY

Detailed explanation-1: -Urine is move down the ureters by means of gravity. Urinary continence is frequently observed in the elderly. Hormones play an important role in regulating the function of the urinary system.

Detailed explanation-2: -The renal pelvis narrows to become the ureter of each kidney. 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.
