Physiology is the study of how our bodies work at the molecular, cellular, and organ systems levels. Understanding human physiology is therefore a key part of knowing ourselves. And of course, knowing what's normal is crucial to understanding the abnormalities that lead to disease, and enabling development of effective treatments.
The importance of Physiology is recognised by the fact there is a specific Nobel Prize category for Physiology and Medicine.
Although much has been learned, mysteries still remain – will you be involved in solving them?
