- Unit 1
- Cause of diesease
- Pathogen cause disease
- Disease is "a description of certain symptons either physical or mental or both"
- Considered a pathogen if: gains entry to host, colonise, resists, damage to tissue
- Infection
- Leads to disease when reconisable symptoms
- Infection
- Transmission: pathogen is transferred from one individual to another
- Pathogens get into body by penetrating organism's interfaceswith environment
- External environment - Internal environment
- Common entry points: Gas exchange surface & Digestive systerm
- Natural Points of entry: Mucous layer, Enzymes, Stomach acids
- Common entry points: Gas exchange surface & Digestive systerm
- External environment - Internal environment
- How: Damaging host tissues & Produce toxins
- Data & Disease
- Correlation: Change in one of two variables reflected by a change in the other.
- Causal Relationship
- Lifestlye & Health
- Risk "a measure of the probability that damage to health will occur as a result of a given hazard"
- Risk measure %
- Lifestlye chocies: Diet, Smoking, Obesity, Physical activity, Sunlight
- Risk "a measure of the probability that damage to health will occur as a result of a given hazard"
- Pathogen cause disease
- Enzymes & the digestive system
- Chap 2
- Major parts of digestive systerm: Oesophagus, Stomach, Small intestine, Large intestine, Rectum, Salivary glands, Pancreas
- Physical & Chemical

- Carbohydrates
- Carbon, Hydrogen, Oxygen
- Bendicts (song)
- Proteins
- 4 Groups -amino, carboxyl, hydrogen, R

- Hydrophobic - Tail, Hydrophilic - Head
- Emulsion Test
- Cause of diesease
- How: Damaging host tissues & Produce toxins
- Data & Disease
- Correlation: Change in one of two variables reflected by a change in the other.
- Causal Relationship
