  • Immunology
    • Defence mechanisms
      • Non-specific
        • Barriers
          • Protective covering (Skin)
          • Epithelia covered in mucus in nose throat etc
          • Hydrochloric acid in the stomach
        • Phagocytosis
          • Phagocytosis deals with Phagocytes
            • Phagocytes are attracted to the pathogens chemo attractants along a concentration gradient
              • The Phagocyte binds to the pathogen
                • Lysosomes within the Phagocyte migrate towards the pathogen as the phagocyte engulfs it
                  • Once engulfed the Lysosomes brake down the pathogen
                    • The pathogen absorbs the remaining products

                                  • The pathogen absorbs the remaining products
        • Specific
          • Cell mediated Response
            • 1) Pathogens invade our cells
              • 2) Phagocytosis occurs however instead of the pathogens product being absorbed they are displayed on the Cell-Surface membrane.
                • 3) The T helper cells have receptors that compliment the antigens of the pathogens.
                  • 4) The T helper cell rapidly divides by Mitosis to form lots of clones. These clones become:
                    • Stimulants to promote phagocytosis
                    • Stimulate B cells to devide
                      • Memory B cells
                      • Plasma cell
                        • Antibodies
                    • 5) Kill affected cells
                      • Cell mediated Response

                                    • Antibodies
                                • 5) Kill affected cells
            • Humeral Response
              • 1) Pathogen is engulfed by a phagocyte and the antibodies are presented on the Cell surface membrane.
                • 2) T cells complement he antigens and they activate the B cells.
                  • 3) The B cell rapidly divides by mitosis. This produces:
                    • Plasma cells
                      • Plasma cells produce antigens rapidly
                      • Primary Immune Response
                      • Humeral Response

                                • Secondary Immune Response
                                • Remembers the antibodies made for the next attack

                    • Memory B cells

        • Antibodies
          • On separate document
        • Vaccinations
          • Passive
            • Antigens are stimulated to be produce by an external source (Vaccinations)
          • Active
            • When our body produce antibodies on it own ocurde
          • Features of Successful Vaccination Programe
            • Economic and affordable vaccine
            • Few side effects but work at the same time
            • Must be able to be Produced, Transported and Administrated in mass quantity's
            • Must be available to the majority of the population
          • Why vaccinations don eliminate deseases
            • timing is of the essence
            • Pathogen may mutate to quickly before every one is vaccinated
            • People have defective immune systems
            • People may not believe in vaccinations or just not be able to get to them
