    2. Outline general functions of each digestive organ.
    3. Point out chemical secretions necessary for digestion of energy-containing nutrients and in what parts of the gastrointestinal tract they are secreted.
    4. Chart the nutrients that require digestion and the digested products that can be absorbed.
    5. Summarize the role of gastrointestinal motility in the digestion and absorption process.
    6. Predict how the digestion and absorption processes may affect nutritional status and oral health.
