Lungs and Airways

Learn about your lungs and airways

Healthy lungs allow you to breathe easily, without discomfort or pain. They supply oxygen to your bloodstream to keep the rest of your body healthy. When your lungs are healthy, you're more likely to be able to do the activities you love and have a good quality of life.

But some people have problems with their lungs from smoking, disease, or infection. When your lungs are unhealthy, your entire body and activity level can suffer. It's important to know how to deal with certain lung conditions so you can stay active and do the things you enjoy.
