When you breathe in, the air travels down through your trachea (windpipe). It then goes through two tubes to your lungs. These tubes are your bronchi. Bronchial disorders can make it hard for you to breathe.

The most common problem with the bronchi is bronchitis, an inflammation of the tubes. It can be acute or chronic. Other problems include

  • Bronchiectasis – a condition in which damage to the airways causes them to widen and become flabby and scarred
  • Exercise-induced bronchospasm – a breathing problem that happens when your airways shrink while you are exercising
  • Bronchiolitis – an inflammation of the small airways that branch off from the bronchi
  • Bronchopulmonary dysplasia – a chronic lung condition in infants, most often premature infants

When you breathe, your lungs take in oxygen from the air and deliver it to the bloodstream. The cells in your body need oxygen to work and grow. During a normal day, you breathe nearly 25,000 times. People with lung disease have difficulty breathing. Millions of people in the U.S. have lung disease. If all types of lung disease are lumped together, it is the number three killer in the United States.

The term lung disease refers to many disorders affecting the lungs, such as asthma, COPD, infections like influenza, pneumonia and tuberculosis, lung cancer, and many other breathing problems. Some lung diseases can lead to respiratory failure.
