Physiology is the study of how animals work: how they breathe, feed, and interact with their environment. Apart from the intrinsic value of this knowledge, it is also knowledge upon which the health care professions are built. Physiology is of interest to nearly everyone; it is especially important for students who may be thinking of becoming medical practitioners, veterinarians, or other health care professionals.

Zoology is the study of animals: their structure, physiology, development and evolution, and adaptations to their environment. We are animals, and we are surrounded by them. One of the enduring fascinations of Zoology as a subject is that we can learn so much about ourselves and our environment by studying what our fellow creatures do. In Wyoming specifically, there is an abundance of wild animals and much has to be learned about them and how they react to changing climates and habitats.
