1 of 23
Metabolic Rate
The rate at which reactions of your body take place, particularly cellular respiration
2 of 23
Inherited

7 of 23
Microorganism
Bacteria, viruses and other organisms that can only be seen using a microscope
8 of 23
Infectious
Capable of causing infection
9 of 23
Droplet infection
A way of spreading infectious diseases through the tiny droplets full of pathogens, which are expelled from your body when you cough, sneeze or talk
10 of 23
Direct contact
A way of spreading infectious diseases by skin contact between two people
11 of 23
White blood cells
Blood cell which is involved in the immune system of the body, engulfing bacteria, making antibodies and making antitoxins
12 of 23
Immune system
The body system which recognises and destroys foreign cells or proteins such as invading pathogens
13 of 23
Antibiotics

Culture medium
A substance containing the nutrients needed for microorganisms to grow
15 of 23
Agar
The nutrient jelly on which many microorganisms are cultured
16 of 23
Natural selection
The process by which evolution takes place. Organisms produce more offspring than the environment can support so only those which are most suited to the environment - 'the fittest' - will survive to breed and pass on their useful characteristics

20 of 23
Immunisation
Giving a vaccine that allows immunity to develop without exposure to the disease itself
21 of 23
Vaccination
Introducing small quantities of dead or inactive pathogens into the white blood cells to produce antibodies that destroy the pathogens. This makes the person immune to the future infection
22 of 23
Vaccine
The dead or inactive pathogen material used in vaccinations
