    Study Notes

    Functions of the Lymphatic System

    • Houses and supports the cells of the immune system
    • Filters and returns lymph (interstitial fluid) to the blood
    • Keeps blood volume constant
    • Absorbs fats and fat-soluble vitamins from the intestine and sends them to the blood system

    The Spleen

    • Located behind the stomach
    • Composed of red and white pulp
    • Screens blood and breaks down old red blood cells for their iron
    • Contains macrophages that can move out into the body in case of infection

    The Thymus

    • Located behind the sternum
    • Part of MALT (Mucosa-Associated Lymphoid Tissue)
    • Located on either side of the posterior end of the oral cavity
    • Protects against pathogens entering through the throat

    Tonsils

    Palatine Tonsils

    • Located at the back of the mouth
    • Small outcropping of the large intestine with nodules of MALT

    Pharyngeal Tonsils (Adenoids)

    • Located high in the posterior throat
    • Nodules of MALT located in the small intestine
    • Protect against pathogens entering through the throat

    Peyer's Patches

    • Located in the small intestine
    • Composed of lobules
    • Lymphoid organ where immature lymphocytes mature into T lymphocytes
    • Exit through blood vessels

    Small Intestine

    • Large mass of MALT located high in the posterior throat
    • Protects against pathogens entering through the throat

    Appendix

    • Part of the gastrointestinal tract
    • Has a number of Peyer's patches

    Lymph Fluid

    • Composition includes interstitial fluid, proteins, fats, and fat-soluble vitamins
    • Absorbed from the intestine and transported to the blood system

    Lymphocytes

    • Found in lymph nodes, spleen, Peyer's patches, appendix, mucosal surfaces, and tonsils

    Lymph Nodes

    • Small structures containing lymphatic tissues
    • Located along lymphatic routes in prominent areas such as armpits, groin, neck, and knees
    • Filter fluid and trap invading cells

    Lymphatic System

    • A one-way system, lacking a defined pump like the heart
    • Flow of fluid through lymphoid vessels relies on the respiratory pump, valves, and skeletal muscle pump
    • Lymphatic capillaries pick up excess fluid from tissues and drain into veins near the heart
    • Fluid passes through lymphatic nodes that filter the fluid and trap invading cells
    • Three primary functions: maintaining fluid balance, facilitating absorption of dietary fats, and enhancing the immune system
