    • Amylase: Enzyme in saliva that breaks down starch
    • Appendix: Tubular organ at the end of the cecum that acts as a source of immune cells
    • Bile: Yellow-green fluid secreted by the liver that aids in digestion
    • Cecum: Blind pouch that begins the large intestine

    • Enteric nervous system: Network of nerves that innervates the digestive system

    Gastrointestinal System Overview

    • Functions: Ingestion, Digestion, Absorption, Defecation
    • Two Main Groups: Alimentary Canal and Accessory Digestive Organs

    Organs of the Alimentary Canal

    • Mouth: oral cavity, mucous membranes, lips, hard palate, soft palate, uvula, vestibule, oral cavity proper, tongue, tonsils, and lingual frenulum
    • Pharynx: passageway for air, fluids, or food; oropharynx and laryngopharynx
    • Esophagus: tube connecting the pharynx to the stomach composed of layers of muscles; conducts food by peristalsis
    • Stomach: C-shaped organ with regions (cardia, fundus, body, and pylorus); involved in mechanical and chemical digestion; produces chyme for transport to the small intestine
    • Small Intestine: Highly coiled tube with regions (duodenum, jejunum, and ileum); digests and absorbs nutrients, aided by various enzymes. Has structural modifications like villi to maximize surface area
    • Large Intestine: Wider but shorter tube than the small intestine; regions (cecum, appendix, colon, rectum, and anal canal); absorbs water and eliminates undigestible waste (feces)
      • Colon: subdivided into ascending, transverse, descending, and sigmoid portions
    • Anal Canal: Canal at the end of the large intestine; involved in defecation
    • Rectum: part of the large intestine involved in the storage of feces

    Accessory Digestive Organs

    • Teeth: masticate food
    • Salivary Glands: produce saliva with amylase to digest starch
    • Pancreas: produces enzymes for digestion, bicarbonate for neutralising acidic chyme
    • Liver: produces bile, emulsifies fats; involved in many metabolic processes
    • Gallbladder: stores bile secreted by the liver; releases bile into the small intestine
