2. As animals increase in physical size, their internal volume grows cubically (r³) while their outer surface area only increases quadratically (r²). This mathematical constraint presents a severe challenge for internal transport and metabolic maintenance.
d) Identify two distinct organ systems in the human body that have evolved complex, highly folded internal microstructures specifically to bypass this surface area limitation. For each system, identify the specific anatomical structure involved (e.g., a cellular or tissue-level structure) and describe how its specialized shape maximizes functional capacity. (5 points)
