Having the shape or form of alveoli; resembling a cluster of small cavities or pits.
From 'alveolar' plus '-form' (from Latin 'forma' meaning 'shape'), literally meaning 'having the shape of alveoli.'
Alveolariform structures appear throughout nature—honeycomb, lung tissue, and even certain sponges use this pocket-filled design because it maximizes surface area while minimizing material, one of evolution's favorite engineering solutions!
