2. Pharynx: It is very short, narrow but muscular tube that opens into oesophagus. 

3. Function: Conduction of food into the oesophagus. 

4. Oesophagus: It is slightly long and narrow tube which opens into crop. 

5. Crop: Crop is a large, pear shaped and sac- like organ. 

6. Function: It temporarily stores the food and then sends it to gizzard.

7. Gizzard: Gizzard or proventricuius is a small spherical organ. It is provided internally with a circlet of six chitinous teeth and backwardly directed bristles.The foregut ends with gizzard. 

Function: The chitinous teeth present in gizzard are responsible for crushing the food and the bristles help to filter the food.
