Objectives On completion of this subject students will be able to explain the mechanisms of some major body functions and how these functions contribute to homeostasis; explain the processes involved in the formation of urine and discuss the roles played by the kidneys in homeostasis; explain the processes involved in the regulation of fluid, salt, water and acid-base balance; explain the processes involved in the supply of oxygen and removal of carbon dioxide from body cells by the respiratory system; describe the principles of cardiovascular physiology with reference to the maintenance of cardiac output and blood pressure; describe the functions of blood and its constituents; describe the general mechanisms of body temperature regulation; explain the role of the cardiovascular system in protecting the body from disease-causing organisms; explain how nutrients, water and electrolytes are transferred from the external to the internal environment by the digestive system; list the six major nutrient categories and note the important dietary sources and principal uses of each; and discuss the relative importance of adjusting metabolic energy expenditure and adjusting food intake as mechanisms for regulating total body energy balance.

Synopsis PHY2627 (Physiological function), relies on foundation studies in BIO1627, which provided an overview of the normal physiology of some of the systems of the body. PHY2627 focuses on the human as a subject for a more detailed study of physiology, emphasising the close relationship between structure and function. The course will focus on the mechanisms of body function in relation to the maintenance of a constant internal environment (homeostasis). Body systems discussed include the respiratory, circulatory, urinary and digestive systems. The interrelationships between these systems will be emphasised.

Assessment Final examination: 70%
