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).
Chest radiography can evaluate the size, shape, and position of the heart. Heart enlargement, for example, may indicate heart disease. Chest radiographs also evaluate the lungs for abnormalities. Normally, the lungs should be filled with air, so they should appear relatively dark on a radiograph. If there is other material in the lungs, such a fluid, blood, or scar tissue, the lungs will appear brighter than normal. Fluid in the lungs may suggest pneumonia, hemorrhage (bleeding), heart disease, or another illness. Other densities in the lungs may suggest a tumor, scar tissue, or other abnormality.
