At this time urine flows out of the bladder and into the urethra. The urethra connects the bladder to the outside of the body.
How does urine move through the body?
· From the kidneys, urine travels down two thin tubes called ureters to the bladder. The ureters are about 8 to 10 inches long. Muscles in the ureter walls constantly tighten and relax to force urine downward away from the kidneys. If urine is allowed to stand still, or back up, a kidney infection can develop.
How does urine pass through the nephron?
· To urinate, your brain signals the sphincters to relax. Then it signals the muscular bladder wall to tighten, squeezing urine through the urethra and out of your bladder. How often you need to urinate depends on how quickly your kidneys produce the urine that fills the bladder and how much urine your bladder can comfortably hold.

Where is urine collected in the kidney?
The center part of the kidney, the medulla (meh-DUH-luh), has fan-shaped structures called pyramids. These drain urine into cup-shaped tubes called calyxes (KAY-luh-seez). From the calyxes, pee travels out of the kidneys through the ureters (YUR-uh-ters) to be stored in the bladder (a muscular sac in the lower belly).

Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.
