Life depends on breathing because the body cells need oxygen. Oxygen is one of the mixtures of gases found in the air. During inspiration, you breathe in or inhale bringing a fresh supply of air into your lungs. During expiration, you breathe out or exhale to get rid of carbon dioxide or waste gases not needed by your body. Hope it helps :)
