Introduction:

The resistance to specific pathogens, their metabolic byproducts or toxins is known as the third line of defense or immunity. Cells of immune system such as, lymphocytes and macrophages are responsible for identification of non-self molecules. Antigens are the non self molecules, which are responsible for generation of an immune response. Humoral immune responses and cellular immune responses are the two types of immune responses generated within the third line of the defense mechanism.
