Abstract

Twenty two dromedary camels in different stages of development were used. The studies showed, unchanging in the position of the esophagus during all the developmental stages. At the pharyngoe sophegeal junction it lies dorsal to the larynx, at the thoracic inlet on the left side of the trachea and its thoracic part lies dorsal to the tranchea. The length, diameter and thickness of its wall increase with the age. The length of the esophagus in adult camel is about 175 cm, and the diameter is about 2.1 cm. In adult camel the cervical part is nearly equal two times the thoracic part in its length but at the same time the thoracic part has a thicker wall and narrower diamerter than the cervical part.
