ANATOMY

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: -The ureters begin at the ureteropelvic junction (UPJ) of the kidneys, which lie posteriorly to the renal vein and artery in the hilum[1]. The ureters then travel inferiorly inside the abdominal cavity. They pass over (anterior to) the psoas muscle and enter the bladder on the posterior bladder aspect in the trigone.

Detailed explanation-3: -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-4: -The renal vein takes blood back to the body after it has passed through the kidney. The renal hilum is the area where the renal artery, renal vein and ureter enter the kidney.

Detailed explanation-5: -The urinary system consists of the kidneys, ureters, urinary bladder, and urethra.
