What does a healthy lung look like?

Answer 1

If you aren't squeamish I would look up a picture. If you are, try to picture this description:

A typical human lung starts just below your clavicle(collar bone) and ends slightly above the third to last rib when deflated. When inflated they can extend to the final rib and possibly slightly below. They are a dark pink color and smooth. Your right lung has a small indent where your heart sits. The lungs contain bronchioles, brachia, and alveolar sacks.
