  1. DIGESTIVE SYSTEM WEDNESDAY, 12/5/2012

  2. DIGESTIVE SYSTEM • Breaks down the food you eat • Before you eat, when you smell a tasty food, see it or even think about it……what happens? • When you eat, saliva helps break down chemicals in the food

  3. ESOPHAGUS • TONGUE pushes food to back of the throat into the ESOPHAGUS. • 10 in. long and moves food to stomach • Muscles in the walls help food to move by squeezing it through the esophagus • Attached to the end of the esophagus is the STOMACH

  4. STOMACH • Shaped like a “J” • Stores food • Breaks down food into a liquidy mixture • Slowly empties mixture into SMALL INTESTINE (sort of like a mixer mashing food together with the help of gastric juices which helps to kill bacteria)

  5. SMALL INTESTINE • 1.5 – 2 in. around; at least 22 feet long • Packed inside of your stomach • Breaks down the food mixture so your body can absorb all vitamins, minerals, proteins, carbohydrates and fats • Food spends as long as 4 hours in small intestine • ….with the help of the pancreas, liver and gallbladder

  6. THE BUDDIES • PANCREAS – makes juices that help the body digest fats and proteins • Juice from the LIVER called bile helps absorb fats into the bloodstream • GALLBLADDER serves as the warehouse for the bile

  7. LIVER • Nutrient-rich blood goes here for processing • Filters out harmful substances or wastes • Helps figure out how many nutrients will go to the rest of the body

  8. LARGE INTESTINE • ¾ in. around, 5 feet long • Packed inside your body • Has a tiny tube at the end called the appendix • After most nutrients are removed from the food mixture…..there is leftover ‘waste’ • This ‘waste’ passes through the part of the large intestine called the COLON.

  9. LARGE INTESTINE • This is where the body gets its last chance to absorb the water and minerals into the blood • As the water leaves, waste gets harder & harder as it moves. It then becomes a solid called…….. • The large intestine pushes it into its very last stop before being extracted.  • Drink water, healthy diet, fiber (fruits, veggies, whole grains)

  10. URINARY SYSTEM

  11. *KIDNEYS – filters waste from the blood and produces urine (IF THEY DO NOT, TOXINS BUILD UP)  *URETERS – two thin tubes that take urine from the kidney to the bladder *BLADDER – a sac that holds urine until time to use the restroom *URETHRA – tube that carries urine from the bladder out of the body
