Physiology is a science concerned with explaining how living organisms work. Ultimately, understanding how living organisms work will allow us to understand what goes wrong in disease and provide a rational scientific basis for treatment of disease. Of the biological sciences, Physiology is highly quantitative and has close links with biochemistry, molecular biology, mathematical modelling, pharmacology as well as zoology and plant biology.
Since the sequencing of the human genome has been completed, the importance of physiology as a discipline has increased dramatically, since the next task is to explain how the inanimate proteins produced by the genetic code are organised and work at the cell and tissue level to enable life to exist. Thus, Physiology is an increasingly important field of study for students interested in any aspect of biology or biomedical sciences.
