LESSON 4
CHAPTER 10

INNATE IMMUNITY

Slide 1 - Tekstslide

Learning goals

  • I understand the difference in innate and adaptive immune system
  • I understand the difference in specific and aspecific immune system
  • I can explain what barriers in the human body contribute to immunity
  • I can explain how phagocytes contribute to immunity


Slide 2 - Tekstslide

Keywords

Innate immunity
Adaptive immunity
Barrier function
Phagocyte
Phagocytosis
Lymphatic system
Lymph nodes


Slide 3 - Tekstslide

Innate immunesystem

Parts of the immune system that are present from birth

Slide 4 - Tekstslide

Adaptive immunesystem

Parts and processes of the immune system that are changing based on previous experiences

Slide 5 - Tekstslide

Lines of defence

The immune system counters attacks from pathogens in three lines of defense:

1. Barriers:           keeping the pathogens out
2. Phagocytes:   attacking and wiping out invaded pathogens 
3. Lymphocytes:    learning from phagocytes how to specifically                                      and effectively kill a certain type of pathogen

Slide 6 - Tekstslide

To what part of the immune system do these lines of defence belong?
Innate immune system
Adaptive immune system
Barriers
Phagocytes
Lymphocytes

Slide 7 - Sleepvraag

Lines of defence

Slide 8 - Tekstslide

Line 1: Barriers

Keeping pathogens out
  • skin
  • mucosal membranes
  • stomach acid
  • antibacterial proteins

Slide 9 - Tekstslide

Note locations in your body that are lined by a mucosal membrane

Slide 10 - Woordweb

Line 1: Barriers

Mechanical barriers                   vs               Chemical barriers
Physical blockages preventing pathogens from entering the body



Attacking pathogens by means of antimicrobial molecules

Slide 11 - Tekstslide

As part of innate immunity, the human body utilises mechanical and chemical immunity Which of the following is an example of chemical immunity?
A
Skin
B
Fluid flow in the urinary tract
C
Stomach acid
D
Mucosal layer in the vagina

Slide 12 - Quizvraag

Explain how washing your skin with soap regularly is countering your immunity.
