  2. Vitamins and Minerals

  3. Nutrition • Taking in nutrients which are organic substances and mineral ions, containing raw materials or energy for growth and tissue repair, absorbing and assimilating them. • http://www.youtube.com/watch?v=s06XzaKqELk

  8. Mechanical and Chemical Digestion • Mechanical • Chewing • Teeth • Peristalsis • http://www.youtube.com/watch?v=rJS-Kh5wCQU • Chemical • Alimentary Canal • http://www.youtube.com/watch?v=ZeUlh9Cou38 • (only watch until you hear what an alimentary canal is) • Enzymes • Amylase • Protease • Lipase

  9. Teeth • Incisors – cutting • Canine – tearing • Premolars and Molars- Grinding

  10. Amylase • In human saliva • Breaks down starches into sugars. • Located in your mouth. Saliva

  11. Protease • Breaks down Protein • (get it PROtease -> PROtein) • Is in your pancreas.

  12. Lipase • Breaks down fat • Found in your stomach

  13. Absorption • The movement of digested food molecules through the wall of the intestine into the blood.

  14. Assimilation • Movement of digested food molecules into the cells of the body where they are used becoming part of the cells.
