THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The area at the center of the kidney. Urine collects here and is funneled into the ureter, the tube that connects the kidney to the bladder.

Detailed explanation-2: -The ureters are bilateral thin (3 to 4 mm) tubular structures that connect the kidneys to the urinary bladder, transporting urine from the renal pelvis into the bladder. The muscular layers are responsible for the peristaltic activity that the ureter uses to move the urine from the kidneys to the bladder.

Detailed explanation-3: -The ureter originates in the renal pelvis and leaves the kidney through the hilus, located at its medial border (Fig. 7-2). The ureter follows a caudal path that is retroperitoneal in the abdominal portion. At the level of the pelvic cavity, the ureter opens into the urinary bladder.
