Why do children sustain more injuries in trauma cases compared to adults?

The correct choice highlights a critical physiological aspect of children's development that contributes to their increased susceptibility to injuries during trauma cases. Children have smaller body sizes and lower body mass compared to adults. When exposed to the same traumatic force, this force is distributed over a relatively smaller area and less mass in children. As a result, the potential for injury is greater because their bodies cannot absorb or withstand the impact as effectively as larger bodies can.

This aspect is crucial to understanding pediatric trauma; given their developing musculoskeletal structure and the fact that children's bones are still growing, they may be more prone to fractures, internal injuries, and other trauma-related issues when a force is applied. In contrast to the other options, which do not accurately reflect the anatomical and physiological realities of children, this explanation addresses the fundamental differences in physical development between children and adults that lead to the increased incidence of trauma-related injuries in pediatric cases.
