Oh wait, do you know if we have to know the bodies line of defences?
Yes you do, its B1.1.2 and the spec states:
c) The body has different ways of protecting itselfagainst pathogens.
d) White blood cells help to defend against pathogens by: ■ ingesting pathogens ■ producing antibodies, which destroy particularbacteria or viruses ■ producing antitoxins, which counteract the toxinsreleased by the pathogens.
e) The immune system of the body produces specificantibodies to kill a particular pathogen. This leads toimmunity from that pathogen. In some cases, deador inactivated pathogens stimulate antibodyproduction. If a large proportion of the populationis immune to a pathogen, the spread of thepathogen is very much reduced.
