![]() Lymphoma can also be the cause of swelling of this lymph node. Lymphoma is one of the 4 type of cancers which is caused by the malignant neoplasm of the lymph cells. which should prompt alert parents to take necessary action. A child that has fallen victim to these condition exhibits symptoms such as constant weight loss, infections, etc. However, it must be noted that there is a remote chance of enlargement observed in children is due to lymphoma. That is why swelling of the lymph nodes in children is a common occurrence. As has been mentioned above, lymphocyte activity against the microorganisms may cause swelling of the lymph nodes. For this reason a child with low lymphocyte level is prone to infections of all sorts. In ChildrenĬhildren depends more, for immunity, on the lymphocytes than on the white blood cells that are present in the blood. The immune system, on detecting these proteins sends more lymphocytes to these nodes which causes swelling of this lymph node. The actual work is performed by the natural killer cells and helper cells, both of which are types of T cells. T cells, a type of lymphocytes, looks for these proteins marked cells and tries to eliminate them. B cells, a type of lymphocytes, mark these pathogens and abnormal cells for destruction using a marker protein. These nodes along with the rest of lymph nodes, employs lymphocytes (white blood cells) to kill microorganisms in the lymph and sanitize it before its onward passage through the system.ĭetection of pathogens or the abnormal cells in the lymph activates lymphocytes. The other function is to protect the body against infections. ![]() The lymphatic system, thorough its lymph capillaries and ducts collects blood plasma (which is now referred to as lymph) and microorganisms and transports it to the lymph nodes which finally drain it into the blood circulatory system. Out here, they are safe from the white blood cells in the blood and can cause the body a great harm. Along with it comes the infectious disease causing bacteria, virus and yeast. Importance of Lymph Nodesĭuring the transportation of blood through the arteries and veins, blood plasma passes through the walls of the blood vessels and gets collected in the spaces between body tissues. In addition to these, some organs such as spleen, tonsils, thymus glands, etc., are also part of this system. This is a vast network of lymph ducts, 500 – 600 lymph nodes, afferent and efferent lymph vessels. To be precise, these nodes are part of the lymphatic system. These nodes are a part of the body’s defensive mechanism against the microorganisms that keeps on attacking. Before we learn about this condition, it is necessary to know about the role of supraclavicular gland and body system they are part of.
