- 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.
