The lymphatic system functions using the immune system by draining fluid accumulated in cells throughout your body. This fluid will help to guard cells by transporting substances such as antibodies, white blood cells, minerals and vitamins throughout your body. There are three big components that form the lymphatic system, they are known as lymphocytes, interferon, and also liquid enhanced protein (FEOP). Lymphocytes are the agents involved with the response to disease, inflammation and disease. Interferon is also an important element in preventing viruses and other dangerous bacteria.
