lymph = fluid from plasma, vessels, tissue - lymph node, organ system - spleen, thymus

maintain blood volume, fat transport - lacteals, defense/protection

skeletal muscle pump, respiratory pump, valves, arterial flow

lymphatic collections vessel where multiple capillaries come together

lymphatic trunks

R&L Lumbar, R&L Bronchomediastinal, R&L jugular, R&L subclavian, intestinal trunk

lower extremities

Lungs & mediastinum

Upper extremities

Head and face

instenines

Thoracic duct & right lymphatic duct

R jugular, R subclavian, R brachomediastinal>> all drain to right subclavian vein

R&L lumbar & intestinal trunk —> cysteran chyli —-> L jugular & L subclavian & L Bronchomediastinal —-> L subclavian vein

Blockage of lymph flow typically by tumor, parasite, or surgical removal

B -cells = regulate immune response / directly attacks invaders, T - cells = produces plasma that produces antibodies

Cells that phatotisizes foreign Debri, also helps activate T cells

Composed of reticular CT, diffuse lymphatic tissue, lymphatic nodules

composed of macrophages and lymphocytes within fibers, major tissue in all lymph organs

Diffuse network of reticular fibers found in most body oprgans

Tightly packed reticular fiber, can also be called Peyers patches when found in intestines

Lymoh node, spleen, thymus, tonsil

Phagocytes remove debris/activate immune system, Lymphocytes monitor for antigens

Site of lymphocyte proliferation, stores breakdown from RBC (Fe), has white pulp (stains purple) and red pulp

Found in spleen, contains lymphocytes and reticular fibers, Stains purple

RBC’s and macrophages break down blood born pathogens and store platelets
