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).
Your lungs sit in your chest, protected by your rib cage. They are large and take up most of the space in your chest cavity, along with your heart. Below your lungs youâll find the diaphragm, which is the large muscle that works with your lungs to help you breathe in (inhale) and out (exhale). Even though you canât see your lungs, itâs very easy to feel them at work. Simply put your hands on your chest and take a few deep breaths. You can feel your chest expand as you inhale and return to its normal size when you exhale.
