(Branta canadensis)

Abstract. Function of the esophageal tonsil of goose, closely connected to mucosa of the esophagus, which forms 7-11 longitudinal folds. There is a transition zone of the goose’s esophagus in the transmission area from the esophagus to the proventriculus. This area loses characteristic for the esophagus prominence, and has a smooth surface. Glands, which are characteristic for the esophagus and the proventriculus, are missed here. As the basis of folds, on the brink with the transition zone, there is an esophageal tonsil, which is presented as blurred bright spots. Lymphoid tissue of the esophageal tonsil, which provides its functional features, is located in the lamina propria and partly in the submucosa, and it is morphofunctionaly matured, because it is presented as all levels of structural organization (diffuse lymphoid tissue, prenodules, primary and secondary lymphoid nodules). The content of structural components of the esophageal tonsil’s lymphoid tissue is uneven. It is registered that the most of it is diffuse lymphoid tissue, much less − primary and secondary lymphoid nodules and the least −Function of the esophageal tonsil of goose, closely connected to mucosa of the esophagus, which forms 7-11 longitudinal folds.
