The structure of the lungs covers some basic GCSE revision. There is a GCSE review on the SNAB website for you to read through and a short test to see if you're up to date. We won't snoop at the test marks and use them against you. Promise.
The main components of the respiratory system are involved in the movement of gases, either into or out of the lungs.
