    Study Notes

    Lymph Node Distribution

    • Lymph nodes are concentrated in the neck, armpits, and groin areas.

    Spleen Function

    • The spleen acts as a filter for the blood, removing old, damaged red blood cells and recycling the iron content.
    • It also stores red blood cells, lymphocytes, and platelets.

    Lymphatic-Bloodstream Interface

    • Lymph enters the bloodstream through the thoracic duct and right lymphatic duct, which empty into the subclavian veins.

    Thymus Responsibility

    • The thymus is responsible for the development and maturation of T-lymphocytes (T-cells).

    Lymphatic Capillaries

    • The main function of lymphatic capillaries is to absorb and transport fats and fatty acids from the digestive system.

    Phagocytic White Blood Cells

    • Phagocytic white blood cells, such as dendritic cells and macrophages, in the lymph nodes engulf and digest foreign particles, bacteria, and dead cells.

    Lymph Vessels

    • Lymph vessels transport lymph throughout the body, allowing for the exchange of substances between the lymph and bloodstream.
    • They also provide a route for immune cells to travel to areas of the body where they are needed.

    B- and T-Lymphocytes

    • B-lymphocytes (B-cells) produce antibodies to fight infections, while T-lymphocytes (T-cells) directly attack infected cells.
    • Both B- and T-lymphocytes are activated in the lymph nodes to mount a specific immune response to pathogens.
