| whats a pathogen | an organism which causes disease effects both animals and plants |

| whats cancer | a group of diseases |
| risk factors of cancer | lifestyle genes |
| whats the 2 types of tumour | benign - non cancerous malignant - cancerous |
| how is type 1 diabetes treat | insulin shots insulin pump |
| are you born with type one diabetes | it can be developed at any age |
| one proven cause of type 2 diabetes | obesity |
| 2 type of disease | communicable non communicable |
| one cause of allergies | immune reaction to a pathogen |
| consequences of coronary heart disease | lack of blood flow to the heart meaning a lack of oxygen |
| examples of virus disease | measles HIV tobacco mosaic virus (TMV) |
| examples of bacterial disease | salmonella gonorrhea |
| examples of fungi disease | rose black spot |
| what's a protist disease | eukaryotes that can causes diseases in humans and animals |
| example of a protist disease | malaria |
| how do you control the spread of a communicable disease | hygiene isolation vaccination |
| how does bacteria make you ill | produce toxins that make you ill |
| how do viruses make you ill | reproduce rapidly inside cells |
| how does skin prevent disease | physical barrier microorganisms that prevent pathogens growing |
| how does the nose prevent disease | mucus to trap particles in the air preventing them entering the lungs |
| how does the stomach prevent disease | strong acid that destroys pathogens in food drinks and mucus |
| what 3 functions do white blood cells have | producing antibodies producing anti toxins phagocytosis |
| what do vaccines contain | small quantities of dead or inactive form of pathogen |
| what is herd immunity | when most of the population is vaccinated against a disease meaning it is less likely to spread |

| example of a non communicable disease | type 2 diabetes cardiovascular disease cancer coronary heart disease |
| what is a risk factor | aspect of lifestyle or substances in the body that can increase the risk of a disease developing |
| risk factor examples | diet alcohol smoking |
| what is the name of the asexual reproduction carried out by viral pathogens inside the body | binary fission |
| why do we need vaccines | to gain herd immunity and prevent the spread of viruses to protect those who are not vaccinated |
| in the UK how do we prevent the spread of salmonella | poultry are vaccinated |
| why is AIDS dangerous | acquired immunity deficiency syndrome,weakens the immune system and makes people more likely to get diseases such as pneumia |
