Question

Quizplus · Accepted Answer

Carbon monoxide is a poisonous gas that binds to hemoglobin in the blood, reducing the amount of oxygen that can be transported to the body's tissues. This can lead to shortness of breath, especially with exertion, as the body struggles to get enough oxygen to meet its needs. Fibrosis of the lungs, chronic bronchitis, and suppressed immune functions are all potential health effects of smoking, but they are not directly related to the inhalation of carbon monoxide.
