Abstract

The main purpose of this study was to give detailed information on the position and normal morphological lower respiratory organs structure in goose which had received a little attention in the field of veterinary anatomy. fifteen  males  adult geese weighing 2-4 Kg were used. The goose was euthanized by the method of inhalation anesthesia .and its body cavity was opened to detect in situ position of thelower respiratory organs. The morphological results of this study show that the trachea appeared long empty cartilaginous flexible pipe , it has pale color and formed from over la The trachea is divided into right and left broncho-syringeal cartilage,  the primary bronchi (extrapulmonary) of the cobra geese consists of incomplete C shaped cartilages rings. pping series of complete tracheal rings which tightly connected to gather. The cartilaginous rings were ossified , these rings are ossify as age progressive the complete cartilaginous ring is to prevent the collapes of trachea due to the negative pressure , which may occur by the inspiration, it was long comparably the neck .
There were some similarities and some differences of the anatomical structures of lower organs of goose and that of other bird species.
