Swollen right supraclavicular lymph node Biology Diagrams Lymph nodes are located throughout the body. They are small, bean-shaped glands that play a crucial role in the immune system. During an infection, a person may notice swollen lymph nodes. Throughout the human body, there are about 500 to 600 lymph nodes which are disseminated widely in clusters mostly in the underarm, neck, groin, chest, and abdomen. These organs are made up of numerous types of cells and tissues, among these, white blood cells and lymphoid tissues are more profuse. A lymph node is a small, bean-shaped structure that is part of the lymphatic system. It acts as a filter for lymph, a fluid containing white blood cells that circulates throughout the body. Lymph nodes are composed of a network of lymphoid tissue and contain immune cells, such as lymphocytes and macrophages. They are critical
A lymph node, or lymph gland, [1] is a kidney-shaped organ of the lymphatic system and the adaptive immune system.A large number of lymph nodes are linked throughout the body by the lymphatic vessels.They are major sites of lymphocytes that include B and T cells.Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles including cancer

There are hundreds of lymph nodes in the human body. They appear in groups, mainly in the neck, under the jaw, around the ears, at the back of the head, in the armpits, groin, chest and abdominal cavity and on the inner sides of the elbows and knees. Chart 1. Lymph Node Locations: HEAD: Preauricular and parotid, Retroauricular, Occipital Location of Lymph Nodes. The size of lymph glands in adults is smaller, as compared to those in children between the age group 10 - 12. Lymph node is located in the lymphatic system, which is distributed throughout the body. It can be present independently or in groups. About 500 - 600 lymph nodes are present in the human body.
How many lymph nodes are in my body? There are approximately 600 lymph nodes in your body as an adult. The exact number varies from person to person. What are lymph nodes made of? Lymph nodes are made of lymph tissue and different types of cells including: White blood cells (lymphocytes). B cells. T cells. Dendritic cells. Macrophages. Plasma Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of
