Explanation:
Detailed explanation-1: -The urine travels from the kidneys to the bladder in two thin tubes called ureters. The ureters are about 8 to 10 inches long. Muscles in the ureter walls tighten and relax to force urine down and away from the kidneys. Small amounts of urine flow from the ureters into the bladder about every 10 to 15 seconds.
Detailed explanation-2: -The ureters are tubular structures, approximately 20–30 cm (7.9–11.8 in) in adults, that pass from the pelvis of each kidney into the bladder. From the renal pelvis, they descend on top of the psoas major muscle to reach the brim of the pelvis. Here, they cross in front of the common iliac arteries.
