Foreign bodies are more frequently located on which side of the body?

Foreign bodies are more frequently located on the right side of the body, particularly in the context of inhaled or swallowed objects. This tendency is attributed to the anatomical differences in the bronchial tree. The right main bronchus is wider and more vertically oriented compared to the left, which makes it more likely for foreign bodies to enter and become lodged there when an individual aspirates.

Moreover, the right lung has three lobes, whereas the left lung has only two, providing a larger volume and surface area where foreign bodies can be trapped. Additionally, many studies and clinical observations have consistently shown that the frequency of foreign body aspiration is significantly higher on the right side, reinforcing the understanding of this anatomical predisposition.

Therefore, the predisposition of foreign bodies being more commonly found on the right side can be effectively linked to these anatomical features and their implications during incidents of aspiration.
