What Are the Names of the Seven Lobes in a Cat's Lungs?

The names of the lobes located in a cat's left lung are the left anterior, left middle and left posterior lobes. Located in the right lung are the anterior, middle, posterior and mediastinal lobes. By comparison, humans have five lobes in their lungs; there are three on the right lung and two on the left.

In cats, as well as in dogs, lung cancer develops in one or more of these lobes. Exposure to smoke or asbestos raises the chances a cat will contract lung cancer. Metastatic tumors, which occur when cancer cells move into the lungs via the bloodstream, are more common than tumors that actually originate in the lungs, states the American College of Veterinary Surgeons.
