Question

How does a birds digestive system work?ФΔФ

Answer 1

From the bill, food moves down a tube called the esophagus and into the crop, which stores excess food so the bird can digest it slowly. The food then moves to the proventriculus, which is the first part of the stomach, where it is softened by gastric acid, mucus, and other digestive juices.

Answer 2

Answer:

Birds have a two part stomach, a glandular portion known as the proventriculus and a muscular portion known as the gizzard. Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and starts the process of breaking down the structure of the food material.
