Proventriculus

Proventriculus

The proventriculus is part of the digestive system of birds, invertebrates and insects. [Encarta World English Dictionary [North American Edition] (2007). "Proventriculus". Source: [http://encarta.msn.com/dictionary_1861736288/proventriculus.html] (accessed: December 18, 2007)]

Birds

The proventriculus is a standard part of avian anatomy. It is generally a glandular part of the stomach that may store and/or commence digestion of food before it progresses to the gizzard. [Source: [http://www.kidwings.com/glossary/proventriculus.htm] (accessed: December 18, 2007)]

The Encarta (2007) holds that the proventriculus is:

...part of bird's stomach: the first part of a bird's stomach, where digestive enzymes are mixed with food before it goes to the gizzard. It is analogous to the gizzard in insects and crustaceans. [Encarta World English Dictionary [North American Edition] (2007). "Proventriculus". Source: [http://encarta.msn.com/dictionary_1861736288/proventriculus.html] (accessed: December 18, 2007)]

Dr. Thomas Caceci (undated) discusses the proventriculus of the avian stomach and opines that:

The proventriculus is the glandular portion of the avian compound stomach, and a rather peculiar organ it is. There's nothing like it in mammals. [Caceci, Thomas (undated). "Proventriculus".
