Question

Smokers often have increased respiratory infections, and one reason is that smoking is known to destroy the cilia lining the respiratory tract. Which type of tissue does this damage?

Answer 1

Elastin is an important protein found in lung tissue that is essential to maintaining the lung's elasticity and ventilatory function. Smoking can cause irreversible damage to elastin—damage that significantly reduces the lung's ability to exchange air efficiently.

Answer 2

The tissue damaged through smoking is;

• the tender tissue of the alveoli and bronchioles located in the lungs

Smoking has been shown to cause damage to the respiratory system thus causing Chronic obstructive pulmonary disease. This results in a lot of death. The lining of the lungs is scarred and damaged due to the particles found in tobacco.

The soft tissue of the alveoli and bronchioles is located in the lungs. Oxygen and other particles move through the capillaries that surround the alveolar walls.

Thus, the lungs do not get clean oxygen when blood passes through it and so, there is damage to the lungs.
