So what is a lymph node and what does it do to the body?
Lymph nodes are small tissue structures that resemble red beans. Lymph nodes can be as small as a pinhead or as big as an olive. There are a lot of lymph nodes in the body and these glands can be found alone or in bundles. A large collection of lymph nodes is present in the neck, inner thighs, underarms, around the intestines, and between the lungs. Lymph nodes have white blood cells that are immune cells that help the body fight infections. The main function of the lymph nodes is to filter out lymph fluids (consisting of fluids and waste substances from body tissues) from nearby organs or areas of the body. Along with the lymphatic vessels, lymph nodes build up the lymph system.
After knowing what is a lymph node, you must understand how the lymph system works. The lymph system is an essential part of the immune system, aka the body’s protection system against illness. The lymph system is a tissue in the body that is formed from the lymphatic vessels and lymph nodes. The lymph system collects fluids, waste matter, and other things (such as viruses and bacteria) in body tissues, outside the bloodstream. Lymph veins carry lymph fluid to the lymph nodes. Once the liquid flows, the lymph nodes filter it, trapping viruses, bacteria and other foreign materials. Then, harmful agents are destroyed by lymphocytes, which are special white blood cells. Then, the filtered liquid, salt, and protein are returned to the bloodstream.
When there are problems such as infection, injury, or cancer, lymph nodes or lymph node groups may be enlarged or swollen as they work against the evil agents. Neck, inner thighs, and underarms are areas where the lymph nodes are often swollen. Therefore, if you experience swelling in areas that have been mentioned earlier, you should check with your doctor.
