Slide 6 - Quizvraag

3.5
The immune system

Slide 7 - Tekstslide

Immune system?

Slide 8 - Woordweb

The immune system
Protects against foreign bodies/ pathogens
 Pathogens = viruses and bacteria

Infection = when a pathogen enters the body

Slide 9 - Tekstslide

Pathogen
Contains DNA (inside)

Has antigens (on the outside)

Slide 10 - Tekstslide

Slide 11 - Tekstslide

Slide 12 - Tekstslide

Natural immunity
1. A pathogen enters your body.
2. You get sick.
3. Your body makes antibodies.
4. You get better.
5. The white blood cells "remember" how these antibodies were made. 
6. The next time the pathogen enters, antibodies are made immediately in large amounts.
7. You are immune.
8. Example: Chicken pox

Slide 13 - Tekstslide

Artificial immunity
1.  Otherwise known as vaccination.
2. You receive a dead or weakened pathogen via an injection. This is known as a vaccine.
3. Specific white blood cells make antibodies.
4. You get a little bit sick.
5. When the pathogen enters again, your bodies make antibodies immediately and in large amounts. 
6. You are immune and will not get sick. 

Slide 14 - Tekstslide

Slide 15 - Tekstslide

Allergic reaction
Allergy - hypersensitive to a particular substance
(food, perfume, dust mites, pollen, etc.)
Causes an immune response in your immune system
- redness, skin rash, burning sensation

Slide 16 - Tekstslide

Anaphylactic response
  • Severe allergic reaction
  • Leads to swollen mucous membranes, thick lips, red blotches shortness of breath
  • Blood vessels can dilate (expand) and blood pressure drops
  • dangerous or fatal if not treated
  • EpiPen - counteracts the anaphylactic response

Slide 17 - Tekstslide

A
Red blood cells
B
White blood cells
C
Platelets
D
Plasma proteins
