Ahola ❗


◾Immunity => Immunity is the ability of an organism to recognize the foreign particles and to mobilize the cells or cell products to speedily remove those foreign particles.

" ÏT provides resistance against disease causing germs "

◾Pathogens => Organisms which cause diseases are called pathogens

◾ Antigens => Any substance that the body regards as foreign and that therefore elicits an immune response, particularly the formation of specific antibodies capable of binding to it.

◾ Allergens => A type of antigen that produces an abnormally immune response in which the immune system fights off a threat that would otherwise be harmless to the body.

◾Histamines =>Chemical found in some of the body's cells -which causes many of the symptoms of allergies, such as a runny nose or sneezing.
