What lungs look like. Here is a diagram of the lungs. If you could see them, they would look pink and rubbery on the outside. Inside they look a lot like sponges. Air comes down the trachea (say trak-ee-a), or windpipe, into two large tubes called the bronchi (say bron-key).
It's a muscle. Your lungs are paired (meaning that you have two of them) The word lung actually means light so that they float.(the only place of attachment in the body is the trachea-so they literally float in the chest). The lung tissue is very porous and made of many small units called alveoli. If stretched out, their area would cover a tennis court! The large area helps the exchange of oxygen gas into the red cells of the blood which will carry the oxygen to other parts of your body. The funny shapes of the lungs are caused by the lungs molding themselves to the surrounding organs in the body. The base is concave to fit over the convex area of the diaphragm. The surface of the lungs lying against the ribs is rounded to match the curve of the ribs. The right lung is thicker and broader than the left.
