Foreign objects refer to items that are not naturally found in a specific environment or context. In medical terms, this can include items like coins, toys, or food that accidentally enter the body, potentially causing harm or obstruction. In other contexts, such as aviation, foreign objects can be anything from debris on a runway to wildlife that poses a risk to aircraft. In everyday life, foreign objects can also refer to items that are misplaced or found in unusual locations. For example, a cell phone left in a refrigerator or a shoe found in a garden can be considered foreign objects. Identifying and removing these items is important to maintain safety and order.
