LESSON 16
The following slides will be discussed during lesson 16

Immunisation and immune disorders

Slide 7 - Diapositive

Immunization
The action and process of making someone immune

Slide 8 - Diapositive

4 categories of immunization

Slide 9 - Diapositive

Passive immunization
a way of immunization in which NO memory cells are formed because the adaptive immune system remained passive

advantage: immunity is obtained almost immediately

drawback: immunity is only for the short term

Slide 10 - Diapositive

Active immunization
a way of immunization in which memory cells are formed because the adaptive immune system was activated

advantage: immunity is long-lasting

drawback: it takes time before immunity is obtained

Slide 11 - Diapositive

Natural vs artificial immunization
natural immunization
the way someone encountered the immunizing agent occured in a natural fashion 

artificial immunization
the way someone encountered the immunizing agent occured in a artificial fashion

Vaccination/immunisation

- Make your own antibodies
--Make long term memory cells
Placenta or breastfeeding

- Mother makes antibodies
--No long term memory cells

Slide 15 - Diapositive

Allergic reaction
  • Exaggerated response against an otherwise harmless antigen (allergen)
  • Common allergens: pollen, mites, nuts, shellfish etc.
  • Antibodies against allergens bind to 'mast cells' (certain type of white blood cell)
  • Histamine is released from mast cells
  • Histamine causes all complaints linked to allergic reaction
  • redness, production mucus, swelling etc
