Swollen Lymph Nodes Lymph nodes are tiny, bean-shaped organs that filter lymph fluid. They are located throughout the body, but particular collections are found just under the skin in the neck, under the arms, and in the groin area. Lymph nodes are part of the lymphatic system, which is one of the body's defense mechanisms against the spread of infection and cancer. Lymph is clear fluid that is made up of water, white blood cells, proteins, and fats that have filtered out of blood vessels into the spaces between cells.

Lymph Nodes - Function, Anatomy, and Cancer These vessels direct lymph toward the lymph node. As the lymph enters the node, spaces or channels called sinuses collect and carry lymph toward an area called the hilum. The hilum is a concave area in a node that leads to an efferent lymphatic vessel. Efferent lymphatic vessels take lymph away from the lymph node.

Medical Dictionary Lymph nodes are small, bean-shaped glands throughout the body. They are part of the lymph system, which carries fluid (lymph fluid), nutrients, and waste material between the body tissues and the bloodstream.The lymph system is an important part of the immune system, the body's defense system against disease.The lymph nodes filter lymph fluid as it flows through them, trapping bacteria, viruses, and other foreign substances, which are then destroyed by special white blood cells called lymphocytes.ymph nodes often swell in one location when a problem such as an injury, infection, or tumor develops in or near the lymph node. Which lymph nodes are swollen can help identify the problem. 1  The glands on either side of the neck, under the jaw, or behind the ears commonly swell when you have a cold or sore throat.

Chest X-ray Abnormalities Hilar abnormalities The hila consist of vessels, bronchi and lymph nodes. On a chest X-ray, abnormalities of these structures are represented by a change in position, size and/or density. Hilar enlargement may be unilateral or bilateral, symmetrical or asymmetrical. In combination with clinical information, each of these patterns is often helpful in reaching a diagnosis. Bilateral, symmetrical hilar enlargement should raise the suspicion of sarcoidosis, particularly if there is evidence of paratracheal enlargement, or lung parenchymal shadowing.
