Lung Disease

Question 1

What is the main effect of fibrosis?

Answer 1

Scar tissue formation

Question 2

Why is the formation of scar tissue bad?

Answer 2

Thicker and less elastic than normal tissue of the lungs.
Increses the difussion pathway- reduced rate of diffussion of gases
Leads to higher ventilation rate
Less elastic- cant recoil and expand as much
Vollume of lungs reduced
Reduced tidal volume
Reduced FVC
FEV

Question 3

What is the main effect of Asthma?

Answer 3

Inflamed bronchi

Question 4

Why is the inflamtaion of the bronchi bad?

Answer 4

Constricts airways through narrowing thier diameter
Reduced air flow in and out of lungs
Less flow of oxygen/ CO2
FEV reduced
Reduced rate of gas exchange in the alveoli- less ox in blood- cells receive less- reduced rate of respiration ATP production- less energy

Question 5

What are the risk factors of lung disease?

Answer 5

Gentics 
Smoking 
Pollution/ environment 
Occupation 
Age
