Risk factors
Choices that can increase chances of getting a specific disease
casual mechanism is
a hypothesis that has a direct link to causing a specific disease

trigger cancers
pathogens causing immune reactions
trigger allergies

cardiovascular disease
obesity
Type 2 diabetes

carcinogens can cause
cancer
skin has a body defence of
barrier defence
nose has a body defence of
hairs trapping pathageons
trachea has a body defence of
mucus which traps pathogens, cilia sweep it back up to be swallowed
stomach has a body defence of
acid destroying pathogens
A pathogen is a
disease causing microbe
bacteria is a
prokaryotic cell, they produce toxins that damage tissue and make the patient feel ill
SIMPLE SINGLE CELLED ORGANISM THAT HAS NO NUCLEUS OR MEMBRANE
A virus is
A virus is a small cell of simple composition that can multiply only in living cells of animals, plants, or bacteria.
Fungi are
one of the 5 kingdoms of life, some cause disease
protists are
Eukaryotic cells , some cause disease
