Axillary Nodes

The axillary nodes are lymph nodes located in the armpits. In the underarm region they receive lymph from vessels that drain the arm, the walls of the thorax, the breast, and the upper walls of the abdomen. Like all lymph nodes, they have the primary function of the production of lymphocytes, which help defend the body against microorganisms and against harmful foreign particles and debris from lymph before it is returned to the blood stream.
