About Lungs and Breathing

The lungs are the main organs in the respiratory system and control breathing. The interior of a lung resembles an upside-down tree; passages at the top of the lungs branch off repeatedly, splitting into smaller and smaller passages before ending in tiny sacs called alveoli. In these alveoli blood comes into contact with the air so the blood can pick up oxygen and release carbon dioxide. If the passages of the lungs become inflamed they can swell, as is the case with asthma. Particulates in the air, whether caused by smog or cigarette smoke, can clog the lungs and make it hard to get enough oxygen. Alveoli can also become swamped with fluids like mucus; this can be a major concern for people with cystic fibrosis or pneumonia.
