proventriculus

Examples of proventriculus in the following topics:

• Vertebrate Digestive Systems

  • The stomach of birds has two chambers: the proventriculus, where gastric juices are produced to digest the food before it enters the stomach, and the gizzard, where the food is stored, soaked, and mechanically ground.
  • Food passes from the crop to the first of two stomachs, called the proventriculus, which contains digestive juices that break down food.
  • From the proventriculus, the food enters the second stomach, called the gizzard, which grinds food.

• Plague

  • While in the insect vector, proteins encoded by Hms genetic loci induce biofilm formation in the proventriculus, a valve connecting the midgut to the esophagus.
  • Ingested blood is pumped into the esophagus, where it dislodges bacteria lodged in the proventriculus and is regurgitated back into the host circulatory system.
