  3. KEY CONCEPTThe digestive system breaks down food into simpler molecules.

  4. In 1822, Alexis St. Martin was shot in the stomach and treated by William Beaumont, an army surgeon • The bullet had left a small hole in his stomach • Beaumont persuaded St. Martin to let him observe the digestive process by tying foods to string, putting them into the stomach, and observing how the food was digested

  5. mouth esophagus liver gallbladder large intestine small intestine rectum/anus The digestive system is a collection of organs that breaks down food into energy that can be used in cells

  6. mouth esophagus liver gallbladder large intestine small intestine rectum/anus • After digestion is complete, nutrients are absorbed and transported to all cells. • Undigested materials are eliminated as liquid and solid wastes (urine/feces)

  7. esophagus muscles relax food Digestion begins in the mouth and continues in the stomach. • Mechanical (teeth) and chemical (saliva) digestion break down food. • Peristalsis moves food through the organs. muscles contract stomach

  8. Digestion of carbohydrates begins in the mouth. • Digestion of proteins occurs in the stomach. • Digestion of fats and sugars occur in thesmall intestine.

  9. gallbladder pancreas duodenum • Most digestion takes place in the small intestines. • The pancreas, liver, and gallbladder aid in digestion. • pancreas helps digest fat and protein • bile from the liver/gallbladder helps digest fats liver stomach bile chyme bile enzymes

  10. Sponge # 9 1. What is the main function of the digestive system? 2. Describe how the mouth uses both mechanical and chemical digestion. 3. What three organs aide the small intestine with digestion? 4. If you ate a meal of spaghetti and meatballs, where would digestion of the pasta begin? The meat?

  11. What is the main function of the digestive system? • To break down food into smaller molecules for the body to absorb and use for energy. • Describe how the mouth uses both mechanical and chemical digestion. • Mechanical: teeth chew food • Chemical: enzymes in saliva break down starches • What three organs aide the small intestine with digestion? • Gallbladder, liver, and pancreas • If you ate a meal of spaghetti and meatballs, where would digestion of the pasta begin? The meat? • Spaghetti: in mouth- starches • Meatballs: in stomach- proteins

  12. Circulatory and Digestive System Posters • Title on top • Describe the FUNCTION (job) of your organ • Draw a picture • Answer all questions on prompt • Color • Use Big font
