The proventriculus is the glandular compartment, which is functionally equivalent to the mammalian stomach. The proventriculus is a fusiform organ that varies in size and shape among avian species, being relatively small in granivorous species and relatively large in carnivorous and piscivorous species (Figs. 1 and 2) .
