Did You Know?
The Latin root physio- generally means "physical", so human physiology deals with just about everything that keeps us alive and working, and other physiology specialties do the same for other animals and for plants. To do anything serious in the field of health, you've obviously got to know how the body's organs and cells function normally. Physiology used to be considered separately from anatomy, which focuses on the body's structures; however, it's now known that structure and function can't easily be separated in a scientific way, so "anatomy and physiology" are often spoken of in the same breath.
