Lungs and Breathing

Many people who are admitted to intensive care are having trouble breathing. Normally, the lungs expand when we breathe in, and shrink back again when we breathe out. When we breathe in, the air fills the small pouches surrounded by tiny blood vessels deep in the lungs. They exchange oxygen that the body needs for carbon dioxide that the body needs to get rid of.
