How do my lungs help me breathe?
Right now, without even thinking about it, you just took a breath. And another. Inside your chest, two soft, springy bags have been quietly working your entire life. They're your lungs — and they're far busier than they look.
It starts with a sniff. Air rushes in through your nose or mouth and slides down a long tube in your throat called the windpipe. Think of it as a hallway — air travels down it, heading deeper into your chest toward the lungs waiting below.
