This sounds a bit like a homework question... –  Brandon Invergo Jul 25 '13 at 10:44

The ureters run from the kidneys to the bladder whilst the urethra runs from the bladder to exit the body:

The renal papillae are the site where urine drains into one of the minor calyxes of the kidney. Multiple minor calyxes join together into a major calyx, and multiple major calyxes join together to form the renal pelvis which then drains into the ureter.
