Q

What part of the respiratory system does asthma affect?

A

Bronchioles. Asthma causes bronchoconstriction

18
Q

How do inhalers for asthma work?

A

They work by relaxing the smooth muscle on the bronchioles, they act as a bronchodilator

19
Q

What part of the respiratory system does cystic fibrosis affect?

A

Bronchus

20
Q

What are the main respiratory muscles?

A

Diaphragm, external intercostal muscles, internal intercostal muscles and abdominal muscles.

21
Q

What are the internal intercostal muscles and abdominal muscles used for?

A

Active expiration during exercise

22
Q

What are the external intercostal muscles and diaphragm used for?

A

Inspiration

23
Q

Is inspiration passive ?

A

No, it requires muscle contraction

24
Q

Is expiration passive ?

A

Yes it relies on recoil forces

25
Q

How does the diaphragm contract during inspiration ?

A

Contacts downwards

26
Q

How do the ribs contract during inspiration ?

A

Outwards

27
Q

What is the tidal volume for an average adult human?

A

0.5L

28
Q

How can tidal volume be measured?

A

Using a spirometer

29
Q

What is tidal volume?

A

The volume of air moving into the lungs at rest

30
Q

What is vital capacity ?

A

Volume of audio from maximal expiration to maximal inspiration

31
Q

How to calculate compliance ?

A

Change in volume divided by change in pressure

32
Q

What is surface tension important for ?

A

Deflating the lungs

33
Q

What does COPD do to lung compliance ?

A

Increases lung compliance

34
Q

Wast dies fibrosis do to lung compliance ?

A

Decreases lung compliance

35
Q

Where is the lowest and height airflow resistance ?

A

Lowest= Bronchioles
Highest= Upper airway

36
Q

What do peoples lungs with COPD have difficulty doing?

A

Have difficulty deflating their lungs

37
Q

What causes fibrosis

A

The laying down of more collagen

38
Q

What causes COPD

A

Smoking destroys the elastin in the lungs

39
Q

What would the x-ray of a COPD patients lungs look like ?

A

Longer, wider lungs
Flattened diaphragm
Reduced mid sternal space

40
Q

What would the x-ray of a patients lungs look like if they had fibrosis?

A

Deflated lungs
Widened mid sternal space
Fluffy areas indicating fibrotic tissue
