ASTHMA AND CO2 LEVELS

What Is Asthma? Asthma (say: az-muh) is a condition that affects a person's airways, which are also sometimes called the bronchial (say: brong-kee-ul) tubes. These tubes lead from the windpipe, or trachea (say: tray-kee-uh), into the lungs. For most kids, breathing is simple: they breathe in through their nose or mouth and the air goes into the windpipe.
