Lymph Tissue Scientific Journals

Lymphoid tissues are organized structures that support immune responses. The bone marrow and thymus are primary lymphoid tissues and therefore the sites of lymphocyte development. The lymph nodes, spleen, tonsils and Peyer’s patches are samples of secondary lymphatic tissue. Chronic inflammation can cause the event of tertiary lymphatic tissue .Fluid from circulating blood leaks into the tissues of the body by capillarity, carrying nutrients to the cells. The fluid bathes the tissues as extracellular fluid, collecting waste products, bacteria, and damaged cells, and then drains as lymph into the lymphatic capillaries and lymphatic vessels. These vessels carry the lymph throughout the body, passing through numerous lymph nodes which filter unwanted materials like bacteria and damaged cells. Lymph then passes into much larger lymph vessels referred to as lymph ducts. The proper lymphatic duct drains the proper side of the region and therefore the much larger left lymphatic duct, referred to as the lymph vessel, drains the left side of the body. The ducts empty into the subclavian veins to return to the blood circulation. Lymph is moved through the system by muscle contractions. In some vertebrates, a lymph heart is present that pumps the lymph to the veins. The primary (or central) lymphoid organs generate lymphocytes from immature progenitor cells. The thymus and therefore the bone marrow constitute the first lymphoid organs involved within the production and early clonal selection of lymphocyte tissues.
