    Study Notes

    Digestion Process

    • Begins in the mouth, where food is broken down into smaller pieces
    • Involves mechanical and chemical breakdown of food

    Esophagus

    • Responsible for transporting food to the stomach

    Enzymes

    • Lipase breaks down lipids (fats) in the small intestine
    • Amylase breaks down carbohydrates in the mouth
    • Trypsin breaks down proteins in the small intestine
    • Pepsin breaks down proteins in the stomach

    Stomach

    • Primary function is mechanical breakdown of food
    • Produces hydrochloric acid and enzymes to aid in digestion
    • Responsible for chemical digestion of proteins

    Liver and Gallbladder

    • Liver produces bile, which is stored in the gallbladder
    • Bile helps to emulsify fats in the small intestine
    • Liver's main function is to detoxify harmful substances

    Small Intestine

    • Jejunum is responsible for the majority of nutrient absorption
    • Villi increase the surface area for absorption of nutrients

    Pancreas

    • Main function is to produce insulin
    • Also produces digestive enzymes to aid in digestion

    Large Intestine

    • Role is to store feces
    • Also absorbs water and electrolytes

    Other Components

    • Epiglottis prevents food from entering the trachea during swallowing
    • Sphincter muscles control the passage of food through the digestive system
    • Appendix is a reservoir for beneficial bacteria
