Morphology

proventriculus = ventriculus (semi-transparent) = pro + ventriculus

The morphemes 'pro-' + 'ventriculus' are analyzable, but the exact biological function and placement are specialized vocabulary.

Etymology

Proventriculus comes from the Latin parts pro- 'before' and ventriculus 'little belly', a bit like the English words ventricle and ventral. So in insects it is the 'little belly before' the main gut that grinds or filters food before digestion.
