Respiratory Organs.

Respiratory Organs.

The Larynx of the dog is affected in various ways. It is called a "little box," and the projecting part of this organ is, in the throat of man, spoken of as "Adam's apple." It opens at the back part of the mouth, and is placed at the beginning of the windpipe. All the air that inflates the lungs must pass through it, but it will permit nothing else to enter with impunity. A drop of saliva, or the smallest particle of salt, will be sufficient to call forth the most painful irritability. In fact the lining membrane of the larynx is the most tender or sensitive structure in the body; and, as parts are exposed to suffering just in proportion as they are endowed with sensation, of course, the organ so finely gifted is often the seat of disease.
