Answers
Answer:
12. When you smoke, the cilia lose some of their ability to push chemicals and other foreign materials out of your lungs. Because of this, toxins remain in your lungs for much longer than they normally would. In response, your body has to cough more to remove the chemicals from your lungs.
13. People with chronic bronchitis have chronic obstructive pulmonary disease (COPD). This is a large group of lung diseases that includes chronic bronchitis. These diseases can block air flow in the lungs and cause breathing problems. The 2 most common conditions of COPD are chronic bronchitis
14. The damage to the alveoli and airways makes it harder to exchange carbon dioxide and oxygen during each breath. Decreased levels of oxygen in the blood and increased levels of carbon dioxide cause the breathing muscles to contract harder and faster.
15 .In a healthy person, the tiny air sacs in the lungs are like balloons. As you breathe in and out, they get bigger and smaller to move air through your lungs. With emphysema, these air sacs lose their stretch. Less oxygen gets into your blood and you feel short of breath.

Explanation:
1. These chemicals get stuck in your body's throat and lungs. Coughing is your body's natural way of clearing these airways. When the cough lasts for a long time after extended periods of smoking, it's known as smoker's cough. Smoker's cough tends to sound different than regular coughing.
