Explain how smoking damages the respiratory system and name two conditions that can develop when a person smokes.

Answer:

The lungs need to remain elastic so they can effectively move oxygen into the body and carbon dioxide out of the body. By smoking, you are actually introducing carbon monoxide into the body, which is toxic. Tars and other chemicals will settle on the cilia of the lungs and cannot be removed; which further degrades the functionality of the respiratory system. Two conditions that develop when a person smokes are emphysema and bronchitis.
