Underwater lung
Your average lung capacity is about 6 litres of air. But even after exhaling there will still be a residual volume of a little over a litre. This is a piece of pig lung being held underwater and squeezed, you can see the bubbles of air leaving the bronchiole tubes from the bottom. Check out the full lung dissection here: http://youtu.be/9xhxALk9gm8
