    Study Notes

    Anatomy of the Digestive System

    • The digestive system is divided into two groups: the alimentary canal and accessory digestive organs.
    • The alimentary canal is a continuous, coiled, hollow, muscular tube with organs like the mouth, pharynx, esophagus, stomach, small intestine, and large intestine.
    • The accessory organs include teeth, tongue, and several digestive glands, which aid in the process of digestion.

    Alimentary Canal Organs

    • Mouth: A mucous membrane-lined cavity where food first enters. It includes the hard palate, soft palate, uvula, and tongue.
    • Pharynx: Also called the gullet. It connects the mouth to the esophagus.
    • Esophagus: Connects the pharynx to the stomach. Roughly 25cm (10in) long.
    • Stomach: A J-shaped organ on the left side of the abdominal cavity. It has different regions: cardiac region, fundus, body, and pylorus. It has a key role in digesting food.
    • Small Intestine: The longest part of the alimentary canal with three sections: duodenum, jejunum, and ileum. Primarily responsible for nutrient absorption.
    • Large Intestine: Wider than the small intestine but shorter. It includes the cecum, appendix, colon, rectum, and anal canal. Its primary role is the absorption of water and formation of feces.

    Accessory Digestive Organs

    • Salivary Glands: Produce saliva for mastication. There are three pairs: parotid, submandibular, and sublingual.
    • Teeth: Involved in mastication or chewing food. Different types of teeth have various functions.
    • Pancreas: A soft, pink, triangular gland that extends to the duodenum, aiding in neutralizing stomach acid via digestive enzymes.
    • Liver: The largest gland in the body, located below the diaphragm, right of the body. Produces bile, which assists in fat digestion and is stored in the gallbladder.

    Digestive System Processes

    • Ingestion: Taking food into the body.
    • Propulsion: Moving food through the alimentary canal (e.g., peristalsis).
    • Mechanical Digestion: Physically breaking down food (e.g., chewing, churning).
    • Chemical Digestion: Breaking down food into simpler molecules using enzymes.
    • Absorption: Taking digested nutrients into the bloodstream. Occurs primarily in the small intestine.
    • Defecation: Eliminating indigestible substances as feces.

    Other Important Information

    • Chyme: The semifluid mass of partly digested food that is released from the stomach into the small intestine.
    • Bile: A digestive juice produced by the liver and stored in the gallbladder; it assists in the mechanical breakdown of fats in the small intestine.
    • Digestive enzymes: Various enzymes aid in catalyzing chemical processes during digestion; they are produced by salivary glands, pancreas, and gastric mucosa.
    • Nutrients: Substances in food used by the body for growth, maintenance, and repair. Examples include carbohydrates, lipids, proteins, vitamins, and minerals.
    • Metabolism: All chemical reactions in the body; includes catabolism (breakdown) and anabolism (synthesis).
