Where does the axillary node drain?

The axillary lymph nodes primarily drain the lymphatic fluid from the upper limb, including the hand, forearm, and arm, as well as parts of the breast and the thoracic wall. They receive lymph from the surrounding tissues and are crucial in filtering it before it enters the central lymphatic system. Ultimately, the lymph from the axillary nodes drains into the subclavian lymphatic trunk, which then empties into the venous circulation at the junction of the internal jugular and subclavian veins.
