Airways Inside the Lungs. Airways Inside the Lungs. The lungs' airways (bronchial tubes) divide into smaller and smaller branches (bronchioles). The airways end in air sacs (alveoli) where oxygen moves into the blood.
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.
