Every breath you take, you are using your lungs! Like many human organs, lungs come in a pair, with a left and right side. Humans' right lung has three lobes, and the left lung has only two, leaving room for the heart underneath. The smallest parts of the lungs are known as the 'alveoli'; this is where oxygen is transferred from the air we breathe into our bloodstream. A typical adult breathes in nearly 3000 gallons of air per day; that's a lot of air going through such small alveoli! All of EcoSmartDesigns' handmade, pewter charm jewelry designs are proudly made in the USA.
