Abstract

Immunology is the science that studies immunity (lat. immunitas - resistance), that is the body's ability to resist the effects of foreign substances (antigens). Immune system is composed of organs and cells dispersed throughout the body. The organs of the immune system also can be called lymphoid organs. Lymphoid organs are structures which emerge and mature lymphocytes. Lymphoid organs can be divided into primary (central) and secondary (peripheral). The primary organs are the thymus and bone marrow, and bursa of Fabricius in birds, secondary organs include the lymph nodes, spleen and lymph tissue associated with mucous membranes. Cells present in the immune system are lymphocites in which we distinguish T and B-lymphocytes and NK cells, phagocytes and dendritic cells. Vertebrate immune system differs depending on the phylogenetic development. Fish have the most simplest immune system. Mammals that are evolutionarily the most developed group of vertebrates have the most developed immune system.
