Supraclavicular lymph nodes are a part of the lymphatic system. The lymphatic system collects blood plasma / lymph and microbes present and conveys it to the lymph nodes that drain in to the circulatory system. Thus, it shields the body from infections. The supraclavicular lymph nodes, (present near the clavicles or the collar bones) like most other lymph nodes, make use of the lymphocytes to get rid of the microbes in the lymph.
Swollen Left Supraclavicular Lymph Node
The left supraclavicular lymph node accumulates lymph via the thoracic duct and from the most of the body.Identifying microbes and abnormal cells in the lymph stimulates the lymphocytes. The B cells mark the abnormal cells and microbes for annihilation using a marker-protein. The T cells looks for these protein marked cells and destroys them. The immune system thus transfers more lymphocytes to the nodes; and results in swelling of the supraclavicular lymph node.
Right Supraclavicular Lymph Node Swelling
The right supraclavicular lymph node collects lymph from the lungs, mediastinum, and the esophagus. It identifies and destroys the microbes and abnormal cells. Thus, during lymphocytic activity, the left supraclavicular lymph node gets swollen.
Causes Of Swollen Lymph Nodes
- When the immune system gets compromised, like in HIV, the risk of infections increases, and the glands get swollen.
- Supraclavicular lymphandenopathy is an important cause, wherein, the lymph nodes get enlarged, and also have a tendency to malignancy.
- Lymphoma, a cancer, may be the cause of supraclavicular lymph node swelling. The T cells and B cells replicate uncontrollably.
- By and large, children have weak immune systems and are prone to infections. Lymphocyte activity against the microbes results in swelling of the lymph nodes.
