What can smoking do to human lungs? Create realistic models of healthy and smoker's lungs.
One of the greatest threats to the human respiratory system is smoking tobacco. Tars, an ingredient in tobacco (cigarettes and cigars), irritates airways and leads to infections and diseases such as cancer and emphysema. Lungs typically become clogged with the sticky tobacco tars, reducing their capacity. Tars also kill the cilia hairs in the trachea, which are responsible for cleaning away infections.
Students find pictures of healthy and smokers' lungs. What are the differences? Healthy lungs are pink. Smoking turns lungs black from the sticky tars. Diseases can destroy lung tissue.
