IMMUNITY In biology immunity is the balanced state of multicellular organisms having adequate biological defences to fight infection, disease or other unwanted biological invasion while having adequate tolerance to avoid allergy and autoimmune diseases. Immunity is the capability of multicellular organism to resist harmful micro-organism from entering it. Immunity involves both specific and non-specific components. The non-specific components act as barriers or eliminators of a wide range of pathogens irrespective of their antigenic make-up other components of the immune system adopt themselves to each new disease encountered and can generate pathogen-specific immunity. An immunity system may contain innate and adaptive components. The innate system in mammalians, for example is composed of primitive bone marrow cells that are programmed to recognise foreign substances and to react. The adaptive system is composed of more advanced lymphatic cells that are programmed to recognise self-substance and not react. The reaction to foreign substances is etymologically described as inflammation, meaning to set on fire. The non reaction to self- substance is described as immunity, meaning to exempt or as immunotolerance. These two components of the immune system create a dynamic biological environment where “health” can be seen as a physical state where the self is immunologically spared and what is foreign is inflammatory and immunologically eliminated “Disease” can arise when what is foreign can not be eliminated or what is self is not spared. Innate immunity, also called native immunity, exist by virtue of an organism constitution, that is it genetic make- up, without an external stimulation or a previous infection. It is divided into two types: (a) Non- specific innate immunity a degree of resistance to all infections in general,(b)specific innate immunity a resistance to a particular kind of micro organism only. As a result some races, particular individuals or breeds in agriculture do not suffer from certain infectious diseases. Healthy ways to strengthen your immune system. Don’t smoke Eat a diet high in fruits and vegetables Exercise regularly Maintain a healthy weight If you drink alcohol, drink only in moderation Get adequate sleep Take step to avoid infection, such as washing your hands frequently and cooking meats thoroughly Try to minimize stress DENNA BASIL 8A എം സി എം എച്ച് എസ്സ് എസ്സ്,പട്ടിമറ്റം കോലഞ്ചേരി ഉപജില്ല എറണാകുളം അക്ഷരവൃക്ഷം പദ്ധതി, 2020 ലേഖനം  സാങ്കേതിക പരിശോധന - Anilkb തീയ്യതി: 20/ 04/ 2020 >> രചനാവിഭാഗം - ലേഖനം
