Where are the lymph nodes located in the body (pictures)?
Lymph nodes are located throughout the body. Some are directly under the skin while others are deep inside the body. Even the most superficial (close to the skin) lymph nodes usually are not visible or palpable (felt by touching), unless they are swollen or enlarged for some reason. They are connected to each other by loosely bound lymphatic vessels. Lymph nodes generally coalesce in different regions in the body where they are responsible for filtering the blood and performing their immunologic function for that particular area of the body. Fluid from the lymphatic vessels eventually feeds into the venous system (veins) in the body.
How do you check for swollen lymph nodes?
Usually your lymph nodes are not visible. Once they enlarge, they can become visible in certain areas of your body. Especially behind the ear, or in your neck or groin, you might notice them as enlarged “bumps.” Enlarged lymph glands are often also can be felt (palpable) by slowly moving your hands around the swollen area. You will be able to determine if they are tender or not.
