cavities

Dentist's drill targets

Cavities are hollow spaces or holes within something solid.

The word appears in anatomy (nasal cavity, chest cavity), dentistry (a cavity is tooth decay that creates a hole), and general description (cavities in the rock formation).

A cavity is simply an enclosed or partially enclosed empty space: The squirrel stored acorns in a cavity in the tree trunk.
