Proventriculus
A thin-walled, glandular stomach found in birds. It precedes the gizzard.
Stomach, Avian
In avian anatomy, the stomach is divided into two parts, the proventriculus (a glandular region that produces digestive enzymes) and the ventriculus (also known as the gizzard, a muscular region that grinds food).
Digestive System
A group of organs stretching from the MOUTH to the ANUS, serving to breakdown foods, assimilate nutrients, and eliminate waste. In humans, the digestive system includes the GASTROINTESTINAL TRACT and the accessory glands (LIVER; BILIARY TRACT; PANCREAS).

Drosophila Proteins
Proteins that originate from insect species belonging to the genus DROSOPHILA. The proteins from the most intensely studied species of Drosophila, DROSOPHILA MELANOGASTER, are the subject of much interest in the area of MORPHOGENESIS and development.
