Beginning at the anterior end we see, when the skin is removed from the bird, two tubes lying along the ventral aspect of the neck. These are the esophagus (1) and the windpipe or trachea (2). In the region where the neck joins the trunk there is a sac-like dilata- tion of the esophagus, the crop (3). Proceeding backwards from the crop the ali- mentary tube passes through the thoracic cavity and as it enters the abdominal cavity
