Lung Function and Disease
Main Objectives for Section 3.1.4
The statements below provide a complete list of the requirements in Section 3.1.4 of the AQA specification for AS Biology. The statements are useful as a
checklist to ensure that you have completed all the requirements in the specification. In most cases, the statements below are very similar to those in the
specification itself.
By the end of this chapter you should:
understand what is meant by the terms respiration, breathing, ventilation and gas exchange
know the structure of the parts of the breathing system ­ the lungs, trachea, bronchi and bronchioles, and understand how their structure is related to
their function
understand how gas exchange occurs in the alveoli and be familiar with the features of the alveoli that make gas exchange rapid and efficient
understand how air is moved into and out of the lungs during inspiration and expiration
understand what is meant by tidal volume and minute ventilation rate and be able to calculate the minute ventilation rate
understand the effects of asthma, fibrosis and emphysema on the lungs and be able to explain how these diseases affect gas exchange and respiration
understand the symptoms and effects of tuberculosis and how the disease is transmitted
understand what is meant by a risk factor
be able to interpret data relating to the effects of risk factors such as smoking and pollution on the incidence of lung diseases such as emphysema and
lung cancer.
In investigative and practical work you should:
be able to interpret data from line graphs showing pressure changes in the lungs during breathing and to describe patterns and trends
understand how evidence linking smoking with lung disease has been collected from studies of large groups of people over long periods of time
understand what is meant by correlation and a causal relationship
appreciate the difficulties and limitations of collecting valid and reliable data to prove a causal relationship between a risk factor and a disease in human
populations, since controlled experiments cannot ethically be done to expose groups to a particular risk factor.
