Tiny Lungs, Smoky Air
Bronchioles and bronchi—tubes that allow oxygen to travel from the mouth into the lungs
- The chemicals in the smoke can cause irritation, swelling, and inflammation in these tubes. This can greatly reduce the size of the path for air, much like breathing through a straw.
Alveoli—tiny air sacs at the tip of the lungs that pass oxygen from the lungs to the blood
- Alveoli continue to develop after birth to help with oxygen exchange in the lungs. Secondhand smoke exposure affects alveoli development. Reducing the amount of oxygen to the body increases the risk of infection.
Surfactant—fluid that lines the inside of the lungs, making it easier for the lungs to expand and pass oxygen to the blood
- Surfactant continues to be produced after birth to keep the lungs expanded. Exposing your baby to secondhand smoke interferes with this development, and may prevent your baby’s lungs from making the right amount of surfactant. Low amounts can affect the ability for your baby’s lungs to expand and contract properly.
Sickness in the Smoke
- Coughing, wheezing, phlegm
- Colds and other viral illnesses
- Lower lung infections like pneumonia and bronchitis
