Lymph nodes are small, bean-shaped structures that are part of the immune system, containing cells that help fight infection. They are located throughout the body but are concentrated in specific areas where they can be felt or checked more easily. These key locations include:
- Neck and head (cervical lymph nodes)
- Armpits (axillary lymph nodes)
- Groin (inguinal lymph nodes)
- Chest
- Abdomen (belly)
- Back of the knees
Lymph nodes act as filters for lymph fluid, trapping bacteria, viruses, and other harmful substances, and contain immune cells that destroy these invaders. They are connected by lymphatic vessels that carry lymph fluid throughout the body
. In summary, your lymph nodes are found in many parts of your body, especially in the neck, armpits, groin, chest, abdomen, and behind the knees
