A lymph gland or lymph node has several functions. It is responsible for keeping the body fluids, blood fluid and cerebrospinal fluid in balance. The total amount of body weight is 60% fluids. The lymph fluids combat and destroy all invading organisms (bacteria, etc.) that enter and endanger the body tissue. The lymph fluid is faintly yellow and slightly opalescent (seen as water in a blister) that carries white blood cells (lymphocytes), a few red blood cells, is collected from the tissues throughout the body, and flows in the lymphatic vessels through the lymph nodes then is added to the venous blood circulation. The lymph node becomes swollen and inflamed when an infection or inflammation (see infections and inflammations) is present in the body. Another job of the lymph is to absorb emulsified fat and pass it on in small, tolerable quantities to the bloodstream. All antibodies, which ensure immunity against infectious diseases, are formed in the lymphatic system. Disorders of the heart, kidneys, and blood vessels is attributed to partial failure of the lymphatic system.
Sore and swollen, tender to the touch. Usually accompanies another condition of the body. Check with your doctor for diagnosis and treatment is swollen lymph glands are found. Some glands are deep in the body and can not be palpated, best to determine the cause before attempting to treat.
