Emphysema is a condition that results in the destruction of alveoli in the lungs? What effect would this have on the body?
Correct answer: A. Lower levels of oxygen in the blood
- A. Lower levels of oxygen in the blood
- B. Higher levels of oxygen in the blood
- C. Lower levels of carbon dioxide in the blood
- D. No effect
Explanation
Emphysema can lead to decreased gas exchange efficiency in the lungs due to the destruction of alveoli. This means that less oxygen is transferred from the lungs into the bloodstream during inhalation. As a result, the concentration of oxygen in the blood may decrease, leading to hypoxemia (lower levels of oxygen in the blood). This can result in symptoms such as shortness of breath, fatigue, and cyanosis (bluish discoloration of the skin due to lack of oxygen).

About Effects of Smoking
Smoking exposes the respiratory system to nicotine, tar and carbon monoxide, damaging cilia, reducing oxygen transport and narrowing or inflaming airways. The topic covers dependence, chronic bronchitis, emphysema, lung cancer and cardiovascular effects, while separating short-term physiological changes from long-term disease.
