Urinary System – filters waste and extra fluid from the blood in the form of urine - Composed of four parts
Part 1 • Kidneys • Two bean shaped organs about the size of a fist • Contain nephrons, which are tiny filtering units • Monitors and adjusts amount of salts and water in blood
Part 2 • Ureters • Two tubes that carry urine from the kidneys to the bladder • Each is about 8 to 10 inches long
Part 3 • Bladder • Hollow, muscular organ located in the pelvic cavity • Stores urine • Stores about 2 cups comfortably for 2 to 5 hours • Part 4 • Urethra • Tube that leads from the bladder to the outside of the body
How do I keep the urinary system healthy? • Drink at least 8 glasses of water a day • Limit your intake of caffeine and soft drinks • This can increase water loss through urine, thus dehydrating your body
Now, go back to your experiment and take a look! What do you notice???
