Which structure in the respiratory system is responsible for the exchange of gases?
Step 1: Understand that the respiratory system is responsible for breathing.
Step 2: Know that the lungs are a key part of the respiratory system.
Step 3: Learn that inside the lungs, there are tiny structures called alveoli.
