- trachea
- bronchi
- bronchioles
- alveoli

- using
limewater
- investigate and describe
the effects of physical
activity on rate and depth
of breathing
- explain the link between physical activity and depth of breathing
Annotations:
- in terms of increased carbon dioxide concentration in the blood, detected by the brain, causing an increased rate of breathing Carbon dioxide lowers the pH of the blood Carbon dioxide is a waste product that needs to be excreted
- explain the link between physical activity and depth of breathing
- explain the role of ..... in
protecting the gas
exchange system from
