Immune System recognizes the identity of foreign substances. Antigens are found on the cells of all organisms and your body is able to identify your own cells and tell when a foreign cell has entered the system. What is the Immune System?. The immune system is a vast network of cells and tissues.. Located throughout your body.. Involves numerous types of cells, organs, proteins, and tissues..
