They are major sites of B and T cells and other white blood cells. Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles and cancer cells, but they do not have a detoxification function. In the lymphatic system a lymph node is a secondary lymphoid organ. The most important function of the lymph nodes is that they serve as multiplication sites for lymphocytes; phagocytic cells within them remove bacteria, viruses, and the like from the lymph stream before it is returned to the blood. Your lymphatic system is a network of organs, vessels and lymph nodes situated throughout your body. Many lymph nodes are located in your head and neck region. Lymph nodes that frequently swell are in this area, as well as in your armpits and groin area. Lymphocytes and antibodies remove pathogens and cell debris as lymph passes through these glands to the thoracic cavity. Lymph nodes also serve to trap and destroy cells from cancerous tumors. Lymph nodes are throughout the body but concentrated in different regions. lymph sacs (primitive lymph sacs) form from endothelial cells. then form buds that branch and form the lymphatic network. lymphoid tissue inducer cells - (LTi) first hematopoietic cells to enter and induce lymphoid tissue development.

The lymphatic system has three functions: The removal of excess fluids from body tissues. Absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system. Production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells).

It helps to protect and maintain the fluid environment of the body by producing, filtering, and conveying lymph and by producing various blood cells. Lymph nodes play an important part in the body's defense against infection. Overall, lymph nodes work like a biological filtering system.

A small bean-shaped structure that is part of the body's immune system. Lymph nodes filter substances that travel through the lymphatic fluid, and they contain lymphocytes (white blood cells) that help the body fight infection and disease. There are hundreds of lymph nodes found throughout the body.

Write its function. Lymph is the fluid that circulates throughout the lymphatic system. An important function of lymph is that it captures the bacteria and bring them to lymph nodes, where they are destroyed. It also helps in the absorption of fatty acids and transport of fat and chyle to the circulatory system.

Lymphoid organs. The immune system is made up of organs that control the production and maturation of certain defense cells, the lymphocytes. Bone marrow. Thymus. Lymph nodes. Spleen. Tonsils. Lymphatic tissue in the bowel and in other mucous membranes in the body. Sources.

Humans have approximately 500–600 lymph nodes distributed throughout the body, with clusters found in the underarms, groin, neck, chest, and abdomen. Lymph nodes of the arm Lateral nodes. Anterior or pectoral nodes. Posterior or subscapular nodes. Central or intermediate nodes. Medial or subclavicular nodes.

1 Answer it is responsible for the removal of interstitial fluid from tissues. it absorbs and transports fatty acids and fats as chyle from the digestive system. it transports white blood cells to and from the lymph nodes into the bones.

The lymph flows into lymph nodes through afferent collecting lymphatic vessels and exits through efferent collecting lymphatic vessels. The lymph not only flows through the lymph node, but some of it is reabsorbed into the blood circulation at the lymph nodes.

Lymph Composition Lymph contains a variety of substances, including proteins, salts, glucose, fats, water, and white blood cells. Unlike your blood, lymph does not normally contain any red blood cells.

What are the functions of the Lymphatic System? To transport fluids back to blood and act as the bodies defense and resistance to disease.

Lymph flows from lymphatic vessels into lymphatic trunks, and finally into collecting ducts where the lymph is disposed into the subclavian veins. Run parallel to blood capillaries in all body tissues. Also made of simple squamous epithelium.

The thymus is special in that, unlike most organs, it is at its largest in children. Once you reach puberty, the thymus starts to slowly shrink and become replaced by fat. By age 75, the thymus is little more than fatty tissue. Fortunately, the thymus produces all of your T cells by the time you reach puberty.
