IPA: /prəˈvɛntrɪkələs/
KK: /prəˈvɛntrɪkələs/
A part of a bird's stomach that helps digest food by secreting enzymes and passing it to the next part of the stomach.
The proventriculus is essential for breaking down food before it reaches the gizzard.
Proventriculus is formed from "pro-" (meaning before) and "ventriculus" (from Latin, meaning little belly or stomach). The word refers to the glandular part of the stomach in birds that precedes the true stomach, hence the meaning of a stomach-like structure before the main stomach.
Think of 'before' ('pro-') and a 'little stomach' ('ventriculus') to remember that proventriculus refers to the part of a bird's digestive system that comes before the main stomach.
