  2. What is the Urinary System? The Urinary System is composed of the kidneys, ureters, bladder, sphincter, and the urethra. It is what makes you pee.

  3. Kidneys: • The shape of the bean. • They are purplish-brownish. • They are behind your ribs. • Produce 1 or 2 liters of urine daily. • Are responsible for maintaining the fluids and salts in the body equally balanced. • They also filter the urea from the blood. • Urea-A by-product of protein metabolism that is formed in the liver. Because urea contains ammonia, which is toxic to the body, it must be quickly filtered from the blood by the kidneys and excreted in the urine.

  4. Ureters: • The ureters are tube-like and connect your kidneys to your bladder. • Transports urine to the bladder, it constantly contracts and relaxes to move the urine to the bladder. • Every 10-15 seconds, trickles of urine flows to your bladder.

  5. Bladder: • It is pear shaped, and located in the pelvic region of your body. • Contracts and relaxes like the ureters. • When relaxed it lets in the urine from the ureters, when it contracts it releases the urine. Making you pee. • Holds about 2 cups of urine, but you start to need to pee when it's about 1 cup full. • Always waits until it is full to release the urine.

  6. Sphincter: • The ring-like muscles that are in the urethra. • They receive the signal to relax or contract. When they contract they hold in your urine, when they relax the release it.

  7. Urethra: • Is the tube-like opening where the urine comes out of. • This receives the signals from the brain, once the bladder is full, to release the urine.

  8. *Weird pee facts* • Your urine is odorless until after it comes out of your body. What you smell then is ammonia. • Drinking turpentine is said to make urine smell like a rose. • Eating beets can turn your urine red. • Vitamin B2 makes it bright yellow. • Certain blue dyes make it blue-green. • L-dopa makes it dark brown.

  9. Rhubarb sometimes makes it brownish or pinkish. • Adult men usually pee in a narrower stream than women do because sex and children can affect the women's tissues there. • Piercing the penis may also affect the stream, since it can cause spraying, split-stream pissing, and so on. After piercing, some men have to cover the hole with their hand in order to urinate normally. • A few recorded uses for urine: • To get rid of acne. • To wash linens. The Romans used to do this.
