what do lungs work with
The heart and lungs are very closely connected. Not only do they fit closely together in the chest, but they also work together to make sure that every part of your body gets the oxygen it needs. In our discussion of how the heart works, we said that blood is pumped from the right side of your heart to your lungs. Just like the air you inhale moves through passageways, the blood that flows through your lungs moves through a set of branching pipes called pulmonary vessels.
