Saunders Respiratory Practice 2025 - Free Respiratory Practice Questions and Study Guide

Children are considered the most vulnerable population to smoke exposure due to several critical factors. Their developing lungs and respiratory systems are more susceptible to the harmful effects of smoke. Because children breathe more air relative to their body weight compared to adults, they can inhale a greater concentration of toxins present in secondhand smoke. Furthermore, children often spend more time indoors where smoke can accumulate, particularly in environments where adults smoke. Exposure can lead to serious health issues, including asthma, respiratory infections, and decreased lung function, which can have lasting effects on their overall health.

In contrast, adults and teenagers, while they are still at risk, typically have more developed respiratory systems that are less susceptible to immediate damage from smoke exposure. Non-smoker adults are also at risk if they are exposed to secondhand smoke but do not have the same heightened vulnerability as young children. This distinction highlights the particular risks children face, making them the most vulnerable group in relation to smoke exposure.
