With a master's degree or a doctoral degree, a physiologist is able work more independently. He may design experiments in order to better understand how certain organ systems, tissues or cells function. Other physiologists work in industry, helping to design medical devices or pharmaceuticals that interact positively with the body's natural biology.

Physiologists who study the biological functions of animals are known as animal or veterinary physiologists. Some physiologists specialize in specific organ systems and are referred to with the names of those systems. A neurologist, for example, is a physiologist who studies the nervous system.
