bodily fluids, physical contact
how do pathogenic bacteria cause damage in the body
produces toxins that damage health cells
how do pathogenic virus cause damage in the body
replicates within cells causing them the cells to damage
how can viral diseases be prevented
use tissue when sneezing

mosquito nets, destroy insect habitats

hand washing, no shared towels

protist
how is malaria spread
by a vector - mosquito
what are the effects of malaria
fever, can be fatal
how is malaria prevented
preventing mosquitoes reproducing, using mosquito nets
what defence towards pathogens are in the nose
contains hairs and mucus to trap pathogens
what defence towards pathogens are in the skin
a physical barrier to pathogens
what defence towards pathogens are in the stomach
contains hydrochloric acid to destroy pathogens
what defence towards pathogens are in the trachea and bronchi
produces mucus to trap pathogens, contains cilia to move mucus for swallowing
