Smoking and Tobacco
Smoke in the lungs
what does the smoke from cigarettes doo exactly to the lungs?
Smoke from cigarettes has several effects on the lungs. One effect is to inflame the airways, which causes excess mucous (phlegm) production, cough, and shortness of breath. Another effect is to gradually destroy the tiny air sacs called alveoli, which exchange oxygen and carbon dioxide, eventually leading to emphysema. Another effect is to create changes in the cells leading to lung cancer.
