A lung is one of the two large organs in your chest that fill with air and help your body take in oxygen and get rid of carbon dioxide. Lungs are essential for breathing and staying alive.
From Old English 'lungen,' related to a root meaning 'light in weight,' because lungs are spongy and filled with air. Similar words exist in other Germanic languages with the same basic meaning.
Your lungs are not just bags—they’re full of tiny air sacs, giving them a surface area about the size of a tennis court. Every breath is a massive, invisible exchange between your body and the outside world happening in complete silence.
