  • Did you hand in your final report?

Do not forget:
  • Submission date: October 25th 

Slide 3 - Diapositive

  • Active / passive / natural / artificial
  • Serum
  • Blood groups
  • Allergic reaction
  • Plasma
  • Red blood cells
  • White blood celles
  • Platelets
  • Antigens

Slide 4 - Diapositive

Learning goals
  • I understand what our blood is made of and how it works.
  • I understand what the various blood groups are and how they can affect each other.
  • I can explain what the concept of immunization means
  • I understand and I can explain the various forms of immunization
  • I can explain what the consequences are of a not properly functioning immune system

Slide 5 - Diapositive

Blood

Blood consists of:
  • Blood plasma
  • Blood cells
  • Platelets


Slide 6 - Diapositive

Blood components
  • Red blood cell (red)
  • White blood cells (purple and blue)
  • Blood platelets (yellow)
  • Blood plasm (not shown)

Slide 7 - Diapositive

Slide 8 - Vidéo

Immunization
  • The action and process of making someone immune.

Slide 9 - Diapositive

4 categories of immunization

Slide 10 - 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 

Slide 11 - 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

Examples: antidote against tetanus (artificial), maternal antibodies (natural)

Slide 12 - 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

Examples: vaccination (active), infection (natural)

Slide 13 - Diapositive

active 
passive 
natural 
artificial
Drag the example to the correct spot in the table
getting infected with the flu-virus
an unborn child receiving mommy's antibodies 
getting your annual COVID-19 shot
receiving an antidote against a snake-bite 

Slide 14 - Question de remorquage

ACTIVE IMMUNISATION           PASSIVE IMMUNISATION
WHO PRODUCES THE ANTIBODIES?
Get the disease

- Make your own antibodies
--Make long term memory cells
Vaccination/immunisation

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

- Mother makes antibodies
--No long term memory cells
Serum (blood plasma containing antibodies)

- Antibodies from serum
--No long term memory cell
artificial
natural

Slide 15 - Diapositive

Slide 16 - Vidéo

Blood types

Slide 17 - Diapositive

Blood types of the AB0 system
Red blood cells carry different kinds of proteins on their membranes.
The most common ones are protein A and protein B

If you have blood type A, your red blood cells only carry protein A
If you have blood type B, your red blood cells only carry protein B
If you have blood type AB, your red blood cells both carry protein A and B
if you have blood type 0 (zero), your red blood cells carry neither

Slide 18 - Diapositive

Foreign blood types
If proteins are recognized as foreign:
  • the innate and adaptive immune system will respond
  • In the end antibodies will be produced against the foreign protein (antigen)
  • these antibodies will form massive antigen-antibody complexes 
  • as a result blood will clot
  • causing the capillaries to clog up
