learning resources

  • Life Substances
  • Following Digestion of a Meal
    • Learning Targets: 1 | 2 | 3
    • Key Terms:
      • amylase: digestive enzymes found in saliva and stomach fluids; breaks starches into smaller molecules such as disaccharides and monosaccharides
      • esophagus: muscular tube that connects the mouth to the stomach; moves food by peristalsis
      • peristalsis: series of involuntary smooth muscle contractions along the walls of the digestive tract that move food from the mouth to the stomach
      • epiglottis: flap of cartilage that closes over the opening of the respiratory tract during swallowing; prevents food from entering the respiratory tract
      • stomach: muscular, pouch-like enlargement of the digestive tract where chemical and physical digestion take place
      • pepsin: enzyme found in gastric juices; begins the chemical digestion of proteins in food; most effective in acidic environments
      • small intestine: muscular tube about 6 m long where digestion is completed; connects the stomach and the large intestine
      • pancreas: soft, flattened gland that secretes digestive enzymes and hormones; products help break down carbohydrates, proteins, and fats
      • liver: large, complex organ of the digestive system that produces many chemicals for digestion, including bile
      • bile: chemical substance produced by the liver and stored in the gallbladder that helps break down fats during digestion
      • gallbladder: small organ that stores bile before the bile passes into the duodenum of the small intestine
      • villus: small projection on the lining of the small intestine that functions in the absorption of digested food; they increase the surface area of the small intestine and increase the absorption rate
      • large intestine: muscular tube through which indigestible materials are passed to the rectum for excretion
      • rectum: last part of the digestive system through which feces passes before it exits the body through the anus
    • reading READING (pdf, Biology: The Dynamics of Life, Glencoe, 2000)
    • notes Notes: Digestive System (pdf) | Flash Cards (pdf) | Digestive System Diagram (pdf)
      Note: use key terms above for your flash cards. Other important information for your cards is listed below.
      • mouth: in your mouth, your tongue moves the food around and helps position it between your teeth so that it can be chewed
      • teeth: chewing is a form of mechanical digestion, the process of breaking down food into smaller pieces; mechanical digestion prepares food particles of chemical digestion
      • salivary glands: salivary glands in your mouth secrete saliva; saliva contains a digestive enzyme called amylase
      • pharynx: the membrane-lined cavity behind the nose and mouth, connecting them to the esophagus
      • appendix: small tube-like extension off the large intestine; is thought to serve as a "safe house" for good bacteria
      • anus: external opening of the rectum

    • The Appendix Debate
    • online toolBuild-a-Body: Digestive System, BrainPOP (web game)
    • concept review Concept Review (pdf)
  • Nutrition
    • Learning Targets: 1 | 2 | 3
    • Key Terms:
      • mineral: inorganic substances that are important for chemical reactions or as building materials in the body
      • vitamin: organic substances required in small amount to maintain growth and metabolism; are either fat-soluble or fat-insoluble vitamins
      • Calorie: unit of heat used to measure the energy content of food, each Calorie represents a kilocalorie, or 1000 calories; the amount of heat required to raise the temperture of 1 mL of water by 1 degree C
    • reading READING (pdf, Biology: The Dynamics of Life, Glencoe, 2000)
