    -Crop
    -Proventriculus
    -Small Intestine
    5aii) -Beak/Mouth: The Beak/Mouth contains glands that secrete saliva, which wets the feed to make it easier to swallow. Also, the saliva contains enzymes, such as amylase, that start the digestion process.
    -Esophagus: The esophagus is a flexible tube that connects the mouth with the rest of the digestive tract. It carries food from the mouth to the crop and from the crop to the proventriculus.
    -Crop: The crop is an out-pocketing of the esophagus and is located just outside the body cavity in the neck region. Swallowed feed and water are stored in the crop until they are p
    -Proventriculus: The esophagus continues past the crop, connecting the crop to the proventriculus. The proventriculus (also known as the true stomach) is the glandular stomach where digestion primarily begins.
    -Small Intestine:The small intestine is made up of the duodenum (also referred to as the duodenal loop) and the lower small intestine. The remainder of the digestion occurs in the duodenum, and the released nutrients are absorbed mainly in the lower small intestine.
