Document Summary
Immunity is the body"s resistance to injury from invading organism. The microbe that causes infection are transmitted to people in 4 ways: direct transmission involved bodily contact, kissing. Indirect transmission: occurs when microbes are passed to an individual via airborne particles, dust, water and soil or food. The transmission of yellow fever, for example oc- curs by this method: mechanical transmission: is the passage of a microbe to an individual by means of a carrier that is not directly involved in the disease process. Transmission of an infection by means of dirty hands, bad water, rats, mice or flies are examples of mechanical transmission. Artificial immunity- shots we receive through vaccinations and inoculations for certain diseases ex. hepatitis, whooping cough. Non-specific immune mechanisms- are a general set of responses to any kind of of infection or disorder. Specific immune mechanisms- always required after birth, fight particular microorgan- isms and their toxins.
