1 - AXILLARY LYMPH NODE - The axillary lymph nodes are present in the under arm or axilla area and they use to drain and filter the lymph of the surrounding area like breast pectoral region and upper arm etc..

2 - INTESTINAL LYMPH NODE - these are associated with the immune surveillance , the homeostasis maintainence and transport of the nutrients and affected in case of diseases.
