    Study Notes

    Lymphatic System

    • The right lymphatic duct drains lymphatic vessels in the right upper quadrant of the body.

    Compression of Lymphatic Vessels

    • Increased pressure and inflammation can cause compression of lymphatic vessels.

    Lymphatic Capillaries

    • Lymphatic capillaries are not present in the central nervous system.

    Lymphatic System Functions

    • The lymphatic system is not responsible for storing nutrients.

    Lymphatic Capillaries Function

    • The primary function of lymphatic capillaries is to absorb and transport lipids and fats.

    Lymphocyte Origin

    • Lymphocytes originate from the bone marrow.

    Lingual Tonsils

    • The function of lingual tonsils is to aid in the immune response by detecting pathogens in the oropharynx.

    Spleen Function

    • The main function of the spleen is to filter the blood and remove old or damaged red blood cells.

    Thymus Gland Location

    • The thymus gland is located in the mediastinum, posterior to the sternum.

    Lymphatic Sinuses

    • Lymphatic sinuses are lymph-filled spaces that allow for the exchange of substances between lymph and blood vessels.
