Your rib cage goes around your lungs and heart to protect them from damage. Your ribs also move when you breathe in and out. Below your lungs is the diaphragm (say dye-a-fram). This is a big muscle that works with your lungs to get air in (inhale) and out (exhale). You can feel how they work together. 1  Put one hand on your chest and the other on the upper part of your tummy. 2  Now breathe in deeply.
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.
