This system includes the bone marrow, spleen, thymus, lymph nodes, and lymphatic vessels (a network of thin tubes that carry lymph and white blood cells). Lymphatic vessels branch, like blood vessels, into all the tissues of the body. Also called lymph system.
Spleen: This largest lymphatic organ is located on your left side under your ribs and above your stomach. The spleen filters and stores blood and produces white blood cells that fight infection or disease.
There are two primary lymphatic organs: the red bone marrow and the thymus gland. The development of white blood cells (haemopoesis) was covered briefly in the section on blood.
The primary lymphoid organs are the red bone marrow, in which blood and immune cells are produced, and the thymus, where T-lymphocytes mature. The lymph nodes and spleen are the major secondary lymphoid organs; they filter out pathogens and maintain the population of mature lymphocytes.
The most common lymphatic disease is lymphedema. It is swelling of a body part caused by a lymphatic fluid buildup in the tissues. Lymphedema most often occurs in the arms and legs, but it can also affect the head, chest, breast, abdomen, and genitals.
The most common diseases of the lymphatic system are enlargement of the lymph nodes (also known as lymphadenopathy), swelling due to lymph node blockage (also known as lymphedema) and cancers involving the lymphatic system, according to Dr.
There are two types of lymphatic drainage which may be used to treat lymphoedema – manual lymphatic drainage (MLD) and simple lymphatic drainage (SLD). Lymphatic draining techniques provide regular stimulation of the lymph vessels under the skin.
Spleen is a 2° lymphoid organ and it is the largest organ among all 5 lymphoid organs.
The liver primarily operates as a metabolic center to maintain homeostasis that includes processing of gut-derived nutrients, the clearance of toxins, and the production of the bile (1). Besides these well-known functions, it is also considered as a lymphoid organ (2).
You can comfortably live without a spleen. This is because the liver plays a role in recycling red blood cells and their components. Similarly, other lymphoid tissues in the body help with the immune function of the spleen.
The internal lymphoid organs include the thymus, spleen, bone marrow and some of the lymph nodes.
There are hundreds of lymph nodes throughout your body. The most well-known places where you'll find lymph nodes are in your armpits, neck and groin.
The lymphatic vessels drain into collecting ducts, which empty their contents into the two subclavian veins, located under the collarbones. These veins join to form the superior vena cava, the large vein that drains blood from the upper body into the heart.
Lymph is a clear-to-white fluid made of: White blood cells, especially lymphocytes, the cells that attack bacteria in the blood and body tissues. Fluid from the intestines called chyle, which contains proteins and fats.
There are two lymph ducts in the body: the right lymph duct and the thoracic duct. There are four pairs of lymph trunks: jugular lymph trunks, subclavian lymph trunks, bronchomediastinal lymph trunks, and lumbar lymph trunks. In addition, the intestinal lymph trunk is unpaired.
19) The simplest lymphoid organs are the lymph nodes.
The skin, i.e. the epidermis and its lymphocytes and perhaps part of the lymphocytes in corium, may function as a first level lymphoid organ. This organ may be completely diffuse, but it may also be concentrated in certain lymphoepithelial micro-organs.
