Respiratory system
Looks like
The last and finest air tubes, the terminal ones leading into respiratory bronchioles whose walls are already dotted with air sacs.
What it does
Mark the switch from carrying air to exchanging gas.
Keeping it well
This is where smoke damage starts: in COPD they narrow and collapse early, trapping air. Stopping smoking at any age slows the decline; spirometry confirms the diagnosis in someone with years of cough or breathlessness.
