• Tar is thick, sticky, dark fluid produced when tobacco burns

• It penetrates the airways and lungs

• It combines with the drying effect of the smoke to paralyze or destroy the cilia

• Contains several substances known as carcinogens

Page 12: Chapter24 smoking

Chronic bronchitis

• bronchi are irritated. As tar builds up, cilia become useless resulting in chronic coughing and excessive mucus secretion

Page 13: Chapter24 smoking

Emphysema

• Involves destruction of the tiny air sacs in lungs

• As walls are destroyed, they lose their elasticity and provide less total surface area for oxygen to be absorbed

• Instead of using 5% of total energy to breathe, now using 80%

Page 14: Chapter24 smoking

Lung cancer

• Leading cause of death in males

• Becoming a more significant cause of death in females
