Detailed explanation-1: -No matter how hard we exhale, our lungs will always retain 1 litre of air in the airways. This makes the lungs only human organs that can float on water4.
Detailed explanation-2: -Your lungs bring fresh oxygen into your body. They remove the carbon dioxide and other waste gases that your body’s doesn’t need. To breathe in (inhale), you use the muscles of your rib cage – especially the major muscle, the diaphragm.
Detailed explanation-3: -Take a deep breath and fill your lungs up with air. This will make you float. Lean your head back so that you are looking up at the sky.
Detailed explanation-4: -As long as your body displaces a weight of water equal to your body weight, Archimedes takes over and you are floating. CWatters said: Your lungs aren’t strong enough to compress air significantly-so your volume is not constant when you breath in and out.
