The body’s defense against various microorganisms that cause disease and illness is the immune system. The immune system attacks these disease causing organisms through a sequence of steps referred to as immune response. The immune system is composed of a number of cells, tissues and organs that work in association, attack the disease causing microorganisms and protect the human body.
