- Infectious Disease B1.2
- Micro organisms
- Viruses
- Much smaller than bacteria
- Enter the bodycells
- They then infect it
- Then reproduce inside it
- The bodycell will then break open
- Then reproduce inside it
- They then infect it
- Not all cause disease
- Fungi
- The ones that do are called PATHOGENS
- Bacteria
- Produce toxin(poisons)
- Not all cause disease
- Fungi
- The ones that do are called PATHOGENS
- Defends itself from pathogens
- White Blood Cells
- Ingest Pathogens
- The WBC recognises the bacterium
- Then surrounds bacterium
- Then engulfs bacterium
- Then releases enzymes
- Then engulfs bacterium
- Then surrounds bacterium
- The WBC recognises the bacterium
- Produce Antibodies
- some bacterium have antigens
- Antibodies have a shape that match the antigens
- Antibodies attach to antigens
- And produces many copies
- Antibodies attach to antigens
- Antibodies have a shape that match the antigens
- some bacterium have antigens
- Produce Antitoxins
- Antitoxins go to the toxins
- and "deactivate it" To make the toxins harmless
- Antitoxins go to the toxins
- Ingest Pathogens
- White Blood Cells
