nephron
B
ureters
C

D
urethra
Explanation: 

Detailed explanation-1: -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-2: -Ureteral peristalsis can be considered as a series of compressive zones, corresponding to waves of active muscular contraction, that move at near-constant speed along the ureter towards the bladder.

Detailed explanation-3: -Ureteral peristalsis is the process by which urine is propelled from the kidney to the bladder, and is generated secondary to contraction of the smooth muscles in the wall of the ureter (1).
