Uses B-lymphocytes produced in the bone marrow, where they also mature. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. There are many different types of B-lymphocytes. The immune system consists of a network of diverse organs and tissue which vary structurally as well as functionally from each other. Some of the main organs involved in the immune system include the spleen, lymph nodes, thymus, and bone marrow. Immunity from disease is actually conferred by two cooperative defense systems, called nonspecific, innate immunity and specific, acquired immunity. The immune system is the body's defence against disease and foreign bodies, under the form of antibody production, tissue rejection and phagocytosis. All rights reserved. The immune system is made up of specialized organs, cells, and tissues that all work together to destroy these invaders. The active protection against pathogens is performed by the immune system There are two branches of immune system: Innate immune system and adaptive immune system Cells of innate immune system are non – specific. An antibody is a specialized defense protein synthesized by the vertebrate immune system. These organs remain spreaded throughout the body. In many species, the immune system can be classified into subsystems, such as the innate immune system versus the adaptive immune system, or humoral immunity versus cell-mediated immunity. Immune System consists of different types of cells and molecules which protect our body against pathogens. Some of these cells are specifically designed for a certain kind of disease.

Active immunity is a resistance to disease through the creation of antibodies by the immune system. In humans, the blood-brain barrier, blood-cerebrospinal fluid barrier, and similar fluid-brain barriers separate the peripheral immune system from the neuroimmune system, which protects the brain. The immune system is spread throughout the body and involves many types of cells, organs, proteins, and tissues. There are two systems of immunity in mammals, cell-mediated immune response and humoral immune response. As opposed to passive immunity, where antibodies are injected into an organism during pregnancy or they are artificially acquired, active immunity requires a process of training immune cells to recognize and counteract foreign bodies.
