MICROANATOMY

Detailed explanation-1: -The UPJ is where the pelvis of the kidney transitions into the ureter and the UVJ is where the ureters enter the bladder. The blood supply to the ureter is segmental.

Detailed explanation-2: -The renal pelvis leads to the ureter on the outside of the kidney. On the inside of the kidney, the renal pelvis branches out into two or three extensions called the major calyces, which further branch into the minor calyces. The ureters are urine-bearing tubes that exit the kidney and empty into the urinary bladder.

Detailed explanation-3: -Urine is made in the renal tubules and collects in the renal pelvis of each kidney. 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.
