Immunity is the body's natural defense against disease. It is a complex system that works to protect us from infection by recognizing and eliminating harmful pathogens, such as bacteria, viruses, and fungi.
There are 2 main types of immunity: innate and adaptive (specific) immunity. Innate immunity is the 1st line of defense against infection. It is present from birth and is nonspecific, meaning that it can protect against a wide range of pathogens. Furthermore, it includes physical barriers, such as the skin and mucous membranes, as well as immune cells and proteins that can attack and destroy pathogens. Adaptive (specific) immunity is the 2nd line of defense against infection. It is acquired through exposure to pathogens or through vaccination. Adaptive immunity is specific, meaning that it is tailored to the specific pathogen that it has encountered. Moreover, it includes B cells, which produce antibodies, and T cells, which destroy infected cells.
