This is what you should have learned in high school about nutrition and digestion, from Jim Buckley, Edwards-Knox Central School, Russell, New York.  Try Mr. Buckley's quiz1 and quiz2 on human digestion for his high school students.

If you don't have your textbook, here is the Digestive System from the On-line Biology book.


DIGESTIVE SYSTEM AND NUTRITION

  • nutrition
  • digestion
  • EVOLUTION OF NUTRITION

    CALORIES and ENERGY

    MACRONUTRIENTS

    MICRONUTRIENTS

    1. VITAMINS
      1. Fat Soluble [Fig. 37.5]: A, D, E, K
      2. Water Soluble [Table 37.4]: B group, C
    2. MINERALS
      1. essential (macro) minerals [Table 37.2]
      2. trace minerals [Table 37.3]

    DIGESTION

    to learn more about the human digestive system, go to HUMAN ANATOMY On-Line.

    1. intracellular digestion [fig 37.2a]
    2. extracellular digestion [Fig. 37.2b]
    3. digestive enzymes

    FEEDING MECHANISMS and ANIMAL DIGESTIVE TRACTS

    1. Continuous Feeders
      1. suspension (filter) feeders: [Box 37.1] [Box 37.2]
      2. deposit feeders
    2. B. Discontinuous Feeders
      1. herbivores
      2. carnivores: predation
      3. insectivores
      4. omnivores
      5. fluid feeders: sanguivores and nectivores
    3. digestive system: ingestion =>digestion  => absorption  => egestion
      1. Incomplete Digestive System
        1. gastrovascular cavity: cnidarians and planarians [Fig. 37.3 a, b]
      2. Complete Digestive System
        1. alimentary canal with mouth and anus [fig 37.3d]
        2. peristaltic contractions (peristalsis) [Fig. 37.13a]
        3. segmentation [Fig. 37.13b]
