 The immune system consists of organs , tissues, cells, and chemical messengers that interact to protect the body from foreign invaders and its own cells which have been internally altered. The chemical messengers are cytokines that are secreted by immune system cells which guide immune cell interactions. Lymphocytes (leukocytes identified as either cells B or T) secrete the lymphokines. Monocytes secrete monokines and macrophages. Interleukins are a form of cytokine that sends messages to direct protective action among the leukocytes. The easiest way to comprehend this mechanism is through the various protection stages of the body.
