AMY-2A Lecture Notes - Lecture 7: Subclavian Vein, Red Pulp, Extracellular Fluid
Document Summary
Tissue fluid leaks out of blood lymph capillaries small lymph vessels lymph trunks lymph ducts l/r subclavian vein. Lumbar: r/l side of lower back, lower extremities/pelvis/lower abdomen. Thoracic/left lymphatic = everything on the left and everything on the right below the right rib cage. Right lymphatic = everything on the right from the rib cage and. White pulp (spleen)- lightly colored islands surrounded by red pulp, surrounds the central arteries of the spleen, it contains reticular fibers and abundant lymphocytes, which are important in the immune response. Follicles- in nodes, masses where lymphocytes concentrate in the outer cortex region, contain germinal centers that contain lymphocytes. Trabeculae- inward extensions (little beams) that divide the lymph organ into sections. Peyer"s patches- group of lymphoid nodules that help prevent the movement of bacteria from the intestine into the blood (in the walls of the ileum and appendix)
