Studying Disease Revision Notes
  1. Preventing Disease
    1. Pathogens
      1. Bacteria
        1. Multiply rapidly in warm and moist conditions.
          1. Microscopic.
            1. Living cells.
              1. When they enter the body, they release toxins that make humans feel ill.
              2. Fungi
                1. Larger fungi include moulds and mushrooms
                2. Viruses
                  1. Genetic material inside a coat of protein.
                    1. Passed through bloodstream.
                    2. Disease-Causing Microbe
                      1. Parasites
                        1. Can cause disease in humans
                      2. White Blood Cells
                        1. Produce antibodies to destroy pathogens
                          1. Bought in when first line of defence is broken
                          2. Type 1: Surrounds and digests the microbes
                            1. Types 2: Produces chemicals called antitoxins
                              1. Type 3: Produces chemicals called antitoxins, which neutralise poisons (toxins)
                                1. Type 4: White Blood Cells produce another type of White Blood Cell called a memory cell, this usually means that you rarely get the disease again as the antibodies are produced quicker.
                          3. NOTE
                            1. Pathogens are not the disease, they CAUSE the disease.
                              1. The period between when the person becomes infected and when the symptoms of the disease start to show is called the INCUBATION PERIOD
                              2. First line of defence is the SKIN
                                1. When you cut or graze yourself the skin is broken so now the microbes can enter the blood, to prevent this the blood will clot, dry and go hard. This forms a SCAB
                              3. Micro-Organisms
                                1. Types: Virus, Bacteria, Fungi and Parasite
                                  1. Killing Micorbes
                                    1. Disinfectants work by killing the microbes , they can kill living cells so they shouldn't come in contact with human tissue.
                                      1. Antiseptics can be used on human tissue because they stop the microbes growing, some antiseptics are weakened forms of disinfectants.
                                    2. Vaccinations
                                      1. Weakened form of the disease
                                        1. Given as an injection or as a drink (polio)
                                          1. When the vaccine enters the body it triggers the immune system to respond, white blood cells produce antibodies to attack the microbe. The body now has defence against the microbe: Antibodies/ Special White Blood Cells called Memory Cells. If microbe then attacks the body then the memory cells produce antibodies to attack it quickly.
                                            1. There can be side-effects
