The proventriculus is a storage organ in fish and flesh eating birds. It is appropriate to a soft diet and secretes digestive enzymes. It contacts the left lobe of the [[Avian Liver - Anatomy & Physiology|liver]] ventrally and laterally. It is related dorso-caudally to the [[Spleen - Anatomy & Physiology|spleen]]. It is more cranial than the [[Gizzard - Anatomy & Physiology|gizzard]] and lies to the left of the midline of the bird. It is spindle/fusiform shaped and is roughly 4cm long. The lumen diameter is similar to the [[Oesophagus - Anatomy & Physiology|oesophagus]]. There is no oesophageal sphincter.

*Mucous cells
*Columnar epithelium
*Basophilic
*Papillae- through which collecting ducts from glands run
*Lamina propria run into the papillae
*Hydrochloric acid and pepsin produced
*Glands in the submucosa
*Single tubular glands are grouped into lobules with a common opening into a papillae
*Serous membrane of mesothelial cells attached to the outer longitudinal layer of muscle
*3 layers of lamina muscularis
*No parietal cells
