Each institution is separately accredited by the Commission on Colleges of the Southern Association of Colleges and Schools.
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).
Each lung is divided into lobes. The right lung has three, but the left lung has only two, thus allowing room to accommodate the heart. Together, the lungsâ tissue surface is almost 40 times greater than the bodyâs outer surface, making the lungs (together) one of the largest organs in the body. Each lung houses a bronchial tree, which gets its name from the intricate network of air passages that supply the lungs with air.
