What Are Axillary Lymph Nodes?
Lymph nodes are small organs that are part of the lymphatic system and are grouped in several areas in the body, such as the neck and the groin. Axillary lymph nodes are those that are located in the arm pit, also called the axilla. The lymphatic system is the complement to the circulatory system, and the nodes are where lymph fluid collects and is filtered as it moves toward the point where it re-enters the bloodstream.
