Disease and Immunity WHOLE TOPIC REVISION - A level (AS) Biology | OCR, AQA, Edexcel

The whole chapter of communicable disease and immunity will be covered in this video. The topics included are:
-types of pathogens (bacteria, fungi, viruses, protoctista/protists) and their modes of action;
-named examples of plant and animal diseases (ring rot, tobacco mosaic virus, blight, black sigatoka, tuberculosis, meningitis, HIV/AIDS, influenza, malaria, ring worm and athlete's foot);
-transmission of pathogens in both plants and animals (direct/indirect);
-the plant defence system (physical/chemical defences and the production of callose and lignin);
-types of immunity;
-the non-specific (innate) immune response (physical defences, inflammation, blood clotting (thrombosis) and phagocytosis);
-the specific (acquired) immune response (clonal selection, clonal expansion, antibody secretion and antibody structure, primary/secondary responses);
-natural/artificial active/passive immunity and vaccination;
-autoimmune diseases;
-treating and preventing disease (medicines and antibiotics).
