Chapter 5 (kerboodle) 
Breathing and respiration
Lesson 5: The pleural membrane and diseases (p67-68)

Slide 1 - Tekstslide

Slide 2 - Tekstslide

Treathing the air
-Moist
-Warmed
-Filtered and cleaned


Epiglottis

Slide 3 - Tekstslide

Mucus
Dust and germs get trapped
Cilia (little hairs) move it up your nose an throat

Slide 4 - Tekstslide

Pleural membrane/cavity
2 pleural membranes (around the lungs and muscles)
Inbetween -> pleural cavity with liquid 

-Prevents seperation of the 2 layers
-Allow volume of lungs to change
-Lubricates the sruface -
  lungs can move easily

Slide 5 - Tekstslide

Thoracic breathing in
  1. Intercostal muscles contract
  2. Ribs move up and pull pleural membrane open
  3. Pleural membrane pulls the lungs open
  4. Air is pulled into the lungs
Abdominal breathing in
  1. Abdominal muscles contract
  2. Diaphragm moves down
  3. Diaphragm pulls pleural membrane open
  4. Pleural membrane pulls the lungs open
  5. Air is pulled into the lungs

Slide 6 - Tekstslide

Thoracic breathing out
  1. Intercostal muscles relax
  2. Ribs move down and push pleural membrane closed
  3. Pleural membrane pushes the lungs closed
  4. Air is pushed out of the lungs
Abdominal breathing out
  1. Abdominal muscles relax
  2. Diaphragm moves up
  3. Diaphragm push the pleural membrane closed
  4. Pleural membrane pushes the lungs closed
  5. Air is pushed out of the lungs

Slide 7 - Tekstslide

Smoking and Asthma

Slide 8 - Tekstslide

Slide 9 - Video

Effects of Smoking
  • Tar -> damages teeth and gums -> Causing decay teeth
  • Loss of smell due to damage nerve endings nose
  • Damaging cilia, which clean the air that goes into your lungs
  • Less oxygen uptake in the alveoli due to toxic carbon monoxide gass exchange instead of oxygen uptake
  • Restriction of the blood vessels and harm of the blood vesssel cells 
  • Mutations in the DNA --> Cancer 

The good news --> Recovery possible! 

Slide 10 - Tekstslide

Asthma
  • Inflammation of the airways
  • airways narrow and swell and produce extra mucus

  • Exact cause is unkown

Slide 11 - Tekstslide

inhalators
-Relax the muscles -> widen up the airways
-Anti inflammatory substances stop the inflamation

Slide 12 - Tekstslide
