Resumen

AbstractIntroduction to the immune system Our body is exposed to pathogenic microorganisms that try to colonize us, cause illness and even compromise our survival. Immune system is the physiological tool consists of a set of molecules, cells and tissues that defend us from attacks caused by pathogens or tumors. In this chapter the relevance of the immune system to ensure our survival is addressed. The innate immune system It represents the first line of defense and it is responsible for quick and efficient responses to pathogens. It provides the time needed to activate the adaptive system and expand and select the best defense to finish them. Cellular components of the innate immune system To perform its defensive function, innate immune system is aided by a set of specialized cells: granulocytes, including neutrophils, leading advocates against fagocitables pathogens, bacteria and fungi, and eosinophils and basophils, which protect us from parasites not phagocitables and helminths. Monocytes, macrophages and dendritic cells destroy microorganisms, processing and presenting them to the adaptive system. Natural killer cells are responsible for eliminating virus-infected cells or tumors.
