What is a common effect of prolonged exposure to carbon monoxide?

Prolonged exposure to carbon monoxide is known to lead to a range of detrimental effects on the body due to its impact on oxygen transport in the bloodstream. The correct choice highlights that nausea and weakness are common symptoms experienced by individuals subjected to high levels of carbon monoxide.

Carbon monoxide binds with hemoglobin in red blood cells much more effectively than oxygen does, which effectively reduces the blood’s capability to carry oxygen to vital organs and tissues. This lack of oxygen can cause hypoxia, leading to a deficiency in energy production and resulting in physical symptoms such as dizziness, nausea, and overall weakness.

This response reflects the body's reaction to inadequate oxygen supply and serves as a warning sign of potential poisoning. Recognizing this effect is crucial in assessing and managing situations where carbon monoxide exposure may be a concern, such as in poorly ventilated spaces with combustion engines or heating devices.
