Lymph nodes produce immune cells to help fight infection. They also filter the lymph fluid and remove foreign material, such as bacteria or cancer. Common areas where lymph nodes can be felt include the armpit, behind the ears, and sides of the neck.

Definition: Lymph is a thin, clear to yellowish fluid that contains white blood cells. Lymph travels throughout your body through the lymph system. Lymphatic fluid helps remove bacteria and viruses from your tissues, transport fat from the small intestine, and supply mature lymphocytes (a type of white blood cell) to the bloodstream.
Pronunciation: limpf
Common Misspellings: Lymphs, limf, limp
Examples:
Your lymph system filters lymph and blood and helps you fight infections. Like your blood system, your lymph system travels everywhere in your body through a network of vessels. If you have a breast tumor that sheds cells into your lymph system, the cancer cells may float along until they get stuck in a lymph node. If breast cancer is found in nearby lymph nodes, your chances of metastasis are greater.
