Physiology is the study of how the body works, and is largely concerned with homeostasis – i.e. how body function is maintained at a relatively constant level in different environments and circumstances. This course considers the physiology of the brain and the nervous system; the heart and the circulatory system; the external respiratory system (lungs, together with transport of oxygen and carbon dioxide in the blood) and the gastrointestinal system. There is also some limited information on the pathophysiology of relevant human diseases. Other aspects of human physiology, involving different tissue and organ systems, are covered elsewhere.
There is a workshop on neurophysiology (the Nernst equation), and practical classes that demonstrate the effects of exercise on blood pressure, the ABO blood grouping system, and the effects of pH on the activity of some key enzymes involved in digestion.
