Organ Chart Mouth • Chemical Digestion • Mechanical Digestion Mouth • Teeth- cut, tear & grind food • Tongue- mixes food & helps in swallowing • Enzymes- in saliva break down carbohydrates Esophagus • Mechanical Digestion Esophagus • Peristalsis-pushes food down to the stomach Stomach • Chemical Digestion • Mechanical Digestion Stomach • Chemical- Hydrochloric Acid (HCl) & Pepsin(enzyme) • Mechanical- Stomach muscle churning food(*most mechanical digestion) • Chyme-what the liquid food is called that the stomach helps create. Small Intestine • Chemical Digestion-most in the system! Small Intestine • Most chemical digestion happens here. Enzymes break down food into nutrients. • Villi absorb nutrients into the blood. Liver • HELPER ORGAN!!!! • Chemical Digestion Liver • Produces bile-that breaks down fats. Sends it to the small intestines. • FOOD NEVER ENTERS… Pancreas • HELPER ORGAN!!!! • Chemical Digestion Pancreas • Sends enzymes to the small intestines to break up fats, proteins & starches. • FOOD NEVER ENTERS… Large Intestine • Chemical Digestion-absorption of water • Mechanical Digestion-creating solid wastes in the rectum Large Intestine • Absorbs water. • Creates solid waste & eliminates it(rectum) • Chemical-absorption of water
