The primary components of the Repiratory System of the Chicken are the Larynx, Trachea, Bronchial Tubes and Lungs.

Bronchial Tubes - narrowing and branching tubes from the major airway to deliver respired air directly to the lungs.

Larynx - the organ in the neck involved in breathing, sound production, and protecting the trachea against food aspiration. The larynx is commonly called the voice box.

Lungs - the lungs are the essential organ in the repiratory system of the chicken and most air-breathing animals.  In the chicken, the lungs are located near the backbone. The lungs function is to transport oxygen from respired air into the bloodstream, and to expell carbon dioxide from the bloodstream back into the atmosphere via exhaled air. 

Trachea - commonly called the windpipe, the trachea is the primary passage way for respired air.
