Mumps
Rubella

4

Which diseases are caused by a bacteria?

Salmonella (food poisoning)

5

How can pathogens spread?

Droplets
Animals
Food
Touch

6

How can the body prevent pathogens from entering

Skin
Tears
Ear wax
Mucus
Stomach acid

7

What does the body produce if pathogens get inside it

White blood cells

8

Name 3 ways that white blood cells stop pathogens

Engulf and kill
Produce antibodies to kill
Produce anti toxins to stop toxins harming us

9

What do white blood cells produce to kill pathogens?

Antibodies

10

What do antibodies do?

Kill pathogens

11

What can viruses and bacteria produce to make us feel unwell?

Toxins

12

What do pathogens have which identifies them?

Antigens

13

White blood cells have a _________ which can remember how to make antibodies in case the pathogen ever comes back.

memory

14

What does an antitoxin do?

Stops toxins from making use feel unwell

15

Name some symptoms of being infected by a pathogen

Headache
Fever
Feeling sick

16

How do bacteria make us feel unwell?

Multiply rapidly
Release toxins

17

How do viruses make us feel unwell?

Multiply inside cell damaging them
Release toxins

18

What is a vaccination/immunisation?

An injection of dead/weakened pathogen which gives protection against the pathogen

19

Describe the steps involved in vaccination/immunisation

-Injection of dead/weakened pathogen
-White blood cells produce antibodies to kill pathogen
-White blood cells produce antitoxin to stop toxins harming
-White blood cells remember how to kill it
-Antibodies rapidly produced if the real pathogen infects you

20

What can overuse of antibiotics lead to?

Resistant strains of bacteria

21

Antibiotics do not work on...

viruses

22

The ideal temperature to grow bacteria in a school is

25 degrees celsius

23

Why would you not grow bacteria in a school above 25 degrees celsius?

Because you could grow pathogens

24

Why do antibiotics not cure a cold/flu?

because cold/flu is caused by a virus
antibiotics do not work on viruses

25

What can be given to ease the symptoms of flu?

painkillers e.g. paracetamol
