- Why increasing surface area speeds up chemical digestion
- The consequence of swallowing unchewed food on nutrient absorption
- Front teeth act as the initial cutters
- Pointed shapes focus force to break through skin or meat
- Flat surfaces are best for mashing plants
- Back teeth perform the final heavy-duty mashing
- Mapping tooth shape to its mechanical function
- The sequence of mechanical breakdown in the mouth
- Unchewed food passes through the system without releasing all its nutrients
- Flat teeth are specialized for crushing grains and leaves
