Word! Lymph Node
Say: limf node
Your wonderful lymph nodes! Lymph nodes are little round or bean-shaped bumps that you usually can't feel unless they become swollen. Lymph nodes are like filters that remove germs that could harm you. They contain lymphocytes, which are special cells that fight infection. Sometimes, germs can cause some of the lymph nodes to swell, so you might feel your swollen lymph nodes on your neck when you have a sore throat. But don't worry — these lumps usually just means your body is cleaning up its act!
