Introduction
The proventriculus is also referred to as the muscular stomach. It is connected by the isthmus to the gizzard.
Structure and Function
- A storage organ in fish and flesh eating birds
- Appropriate to a soft diet
- Secretes digestive enzymes
- Contacts the left lobe of the liver ventrally
- More cranial than the gizzard
- Lies on the midline of the bird
- Spindle/fusiform shaped
- Roughly 4cm long
Histology
- Mucous cells
- Columnar epithelium
- Papillae- through which collecting ducts from glands run
- Lamina propria run into the papillae
- Hydrochloric acid and pepsin produced
- Glands in the submucosa
