  11. 11. The Purpose of the Lungs Your lungs are complex organs, but what they do is take a gas (carbon dioxide) that your body needs to get rid of and exchange it for a gas that your body can use (oxygen). The airways are a series of hollow tubes, which let oxygen enter into the lung tissue as we breathe. Your lungs send oxygen to your heart so the blood can have oxygen in it. The lungs are a pair of spongy organs located inside the rib cage. The right lung has three sections, called lobes, and the left lung has two. How do the Lungs work
