The correct order of structures is mouth, oesophagus, crop, stomach(proventriculus), gizzard, intestine, and anus.
<h3>The digestive tract of birds</h3>
The digestive tract of birds starts from the mouth and ends at the anus.
As the food enters the oesophagus through the mouth, it is pushed down to the first stomach called the proventriculus.
Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and start the process of breaking down the structure of the food material.
Food substances that are hard to digest are transferred to the gizzard. Nutrients are absorbed in the intestines and undigested food substances are removed through the anus.
