System that allows animals to breathe and exchange oxygen and carbon dioxide throughout the body; it is composed of nose, pharynx, larynx, tracheobronchial tree, and lungs.
The respiratory system can be divided into the upper respiratory system, which is composed of the nose and pharynx, and the lower respiratory system which is generally composed of the larynx, tracheobronchial tree, and the lungs. This vital system of the body has many functions including olfaction detection, vocalization production, behavioral cues, filtration and humidification of inhaled breaths, and of course gas exchange. This text will discuss the anatomy and function of the respiratory system as well as domestic animal differences that may be important in a clinical setting.
Upper Respiratory System
The upper respiratory system is composed of the nose and pharynx (Tortora and Derrickson 2009).
The nose allows entrance of an inhaled breath to be carried...
