Abstract

The immune system consists of a complex structural network of specialized cells and molecules in different functions and distributed throughout the body. The distinguishing feature of this system is the ability of specific recognition of molecular fragments, which involves the establishment of ongoing interactions between its components with the various systems that make up the body and potential foreign elements that can penetrate it. This ability of recognition, followed by cell activation and development of effector mechanisms, the immune system gives a significant role among the body's defense mechanisms against infections. The Immune System appeared when vertebrates evolved from primitive invertebrate forms, after which occurs the remarkable fact that this system comprises the sole purpose of defending the body against infection. This text presents a thorough and detailed study of the background, the immune system, how it works, reactions, allergies, and potential toxic food, among other analyzes.
