1.4 Sick lungs

Slide 1 - Tekstslide

1.4 Sick lungs
Asthma
COPD
Smoking/vaping
Hay fever





Slide 2 - Tekstslide

Asthma

Slide 3 - Woordweb

ASTHMA:
With asthma, there is inflammation of the air passages that results in a temporary narrowing of the airways that carry oxygen to the lungs.

Symptoms:
- Coughing               - Shortness of breath
- Wheezing               - Chest tightness

Slide 4 - Tekstslide

Slide 5 - Tekstslide

COPD (Chronic Obstructive Pulmonary Disease)
A group of lung diseases that have similar symptoms and causes

Symptoms:
- Coughing               - Shortness of breath
- Wheezing               - Chest tightness 

The symptoms of COPD and ashtma look the same --> the cause is different


Slide 6 - Tekstslide

Slide 7 - Video

COPD is caused by environmental factors such as smoking. Asthma is mainly caused by genetic factors.

Slide 8 - Tekstslide

Bronchitis
  • Continuous excessive mucus production --> frequent coughing (especially in the morning)
  • Swollen bronchial tubes, sometimes accompanied by fever
  • In many cases from the age of 40 or up
  • Contraction of muscle cells (similar to asthma)
  • Usually caused by smoking


Slide 9 - Tekstslide

Emphysema
  • Makes it harder for oxygen to enter the bloodstream from the lungs
  • it strains the heart and can lead to heart problems
  • The alveoli gets destroyed
  • scar tissue forms in the lungs, making emphysema untreatable and further reducing lung function
  • In many cases from the age of 40 or up
  • Usually caused by smoking


Slide 10 - Tekstslide

Slide 11 - Tekstslide

COPD is a combination of two diseases. Which ones are these?
A
Hay fever & emphysema
B
Emphysema & bronchitus
C
Bronchitus & fibrosis
D
Emphysema & fibrosis

Slide 12 - Quizvraag

Smoking

Slide 13 - Tekstslide

Have you ever smoked a cigarette/vape?
Yes
No

Slide 14 - Poll

Smoking - why is it bad?
  • = a controllable environmental factor
  • Effects --> COPD, addiction to nicotine, damage to ciliated cells in the airways
  • Tar build-up: tar from cigarettes forms a sticky layer in the alveoli, hindering oxygen and carbon dioxide exchange in the lungs

Slide 15 - Tekstslide

Smoking - why is it bad?
  • Carbon monoxide impact: smoking produces carbon monoxide, which reduces oxygen delivery to cells
  • Overall health risks: chemicals
  • Cancer risk

Slide 16 - Tekstslide

Healthy
Smoking

Slide 17 - Tekstslide

Vapen
Vaping

Slide 18 - Tekstslide

Why do young people start  vaping?

Slide 19 - Tekstslide

Slide 20 - Video

If all of my friends smoked, I would smoke too.

Slide 21 - Poll

Hay fever
  • Pollen allergy --> allergic reaction to pollen from grasses and wind-pollinated plant
  • Effect on asthma --> acts as an additional trigger for asthma attacks
  • Body's reaction --> hay fever is an overreaction of the body's defense system to harmles pollen, causing excessive muus production, and itchy, teary eyes
  • Symptoms can look the same of a cold (but a cold is caused by a virus)
  • Treatment options --> medicine, honey
