The Urinary System By: Jocelyn Hernandez, JasminRegalado, Priscilla Torres
The Urinary System • The Urinary System includes two kidneys, two ureters, the bladder, two sphincter muscles, and the urethra.
How the Urinary System works • Your body takes nutrients from food and uses it as fuel to maintain your body. • After your body has taken the nutrients from the food, waste products are left behind in the blood. • The urinary system removes a type of waste called urea from your blood. • Urea, water, and other waste substances, form the urine as it passes through the nephrons(tiny filter tubes)and down a tube called the ureterto the bladder to be flushed out.
The organs of the urinary system (: KIDNEY The kidneys are the organs that clean the blood and rid it of waste. We have two kidneys, but people can live with one. URETER The ureters are the tubes that the urine passes through to go to the bladder. BLADDER The bladder is a pouch-like muscle that holds in urine. SPHINCTER MUSCLES The sphincter muscles are the muscles the prevent urine from leaking from the bladder. URETHRA The urethra is a tube that connects the bladder to the genitals so that the urine can come out.
DISEASES OF THE URINARY SYSTEM • One disease of the urinary system are kidney stones. Kidney stones are hard masses of waste. One type of kidney stone problem occurs when there is too much waste in your urine. Kidney stones often appear in pre-mature infants. There are different types of kidney stones. Some types run in families. Most of these kidney stone problems can be treated.
Treatment of kidney stones • There are many types of treatments for every type of kidney stones. Kidney stone that are really small can be washed down with urine. Kidney stones that are fairly big can be broken down with medicine and be flushed out of your body. If the stones are too big, that they cant be washed down, surgery may be needed, but it is very rare.
Ten facts about the urinary system :D • Asparagus makes your urine smell funny. • Kidneys are the size of two fists. • Kidneys are protected by the lower ribs. • About 400 gallons of blood flow throughout our kidneys everyday. • Urine is 5% urea and 95% water.
Urinating frequently can be a sign of pregnancy. • The ureters measure from 8 to 10 inches long. • In around 10 to 15 seconds, ureters empty small doses of urine into the bladder. • If you hold your urine for a long time, you can get a very serious kidney infection. • The nervous system cooperates with urinary system to send the sensation of having to go “pee.”
