Mediastinal Lymph Node
The Mediastinal Lymph Node (pronunciation: me-dee-as-ti-nal limf node) is a significant part of the lymphatic system that is located in the mediastinum, the central compartment of the thoracic cavity.
Etymology
The term "mediastinal" is derived from the Latin word "mediastinus," which means "in the middle," while "lymph node" comes from the Latin "lympha," meaning "water," and the Old English "node," meaning "knot."
Function
The Mediastinal Lymph Nodes play a crucial role in the body's immune response. They filter lymph, a clear or white fluid that carries white blood cells, particularly lymphocytes, which are essential for the body's defense against infections and diseases.
