  5. Digestive System Three functions : 1) Take in and break down food 2) Absorb nutrients 3) Remove solid waste http://yucky.discovery.com/flash/body/pg000126.html

  6. Types of Digestion: Mechanical Digestion: food is broken down by grinding action of teeth and squeezing of muscles Chemical Digestion: food is broken down by action of chemicals like hydrochloric acid and enzymes (e.g. saliva)

  7. Four Stages of Digestion Ingestion: mouth and teeth grind food. Peristalsis (muscular contractions) helps push food down the esophagus. • Digestion: stomach turns solid food into chyme (liquid goop) and sends it to the small intestine.

  8. Absorption: most nutrients are absorbed in the small intestine. Egestion: waste material is sent to the large intestine where water is absorbed. Final waste product (feces) is released through the anus!
