Topic 3 - Analysing Data On Lung Disease [10]

Question 1

Points for Analysing graphs

Answer 1

Positive/Negative Correlation
Data overlapping
Correlation does not prove causation, maybe other factors like genetics or pollution.
No Correlation coefficient statistic to know if correlation is significant.

Question 2

Name 4 types of Lung Disease

Answer 2

Pulmonary Fibrosis
Asthma
Emphysema
Bronchitis

Question 3

Formula for Pulmonary Ventilation?

Answer 3

Pulmonary ventilation = tidal volume x ventilation rate

Question 4

What is pulmonary ventilation?

Answer 4

the total volume of air that is moved into the lungs during one minute (dm^3min^-1)
also known as Breathing

Question 5

Total Lung capacity?

Answer 5

Vital capacity + Residual capacity (normally 5-6dm^3)

Question 6

Residual Volume ?

Answer 6

Volume of air left in lungs after the strongest exhalation

Question 7

What is Vital capacity?

Answer 7

It is the total amount of air exhaled after maximal inhalation.

Question 8

What is Tidal Volume?

Answer 8

volume of air that enters and leaves the lungs at normal resting breath (0.5dm^3)
