Synopsis

The overall theme of this unit is how the body maintains a normal internal environment ('homeostasis') for optimal body function. It examines the roles of three major body systems that are vital for homeostasis: the respiratory system and gas exchange, the cardiovascular system and delivery of blood and nutrients, the kidneys and maintaining body fluid composition. Attention is focused on each system at rest and in a variety of active states, and on control mechanisms in each system. In addition to the core physiology, common dysfunctions of these systems are also studied, to allow for a greater understanding and appreciation of both the normal physiology and dysfunction of these systems.

Outcomes

On completion of this unit, students will have achieved a basic knowledge and understanding, appropriate to a Level 2, 1st semester unit, of the structure and function of the respiratory system, the cardiovascular system and the autonomic nervous system, and the renal system; understood how the respiratory system functions physiologically, physically and chemically in gas exchange to maintain an optimal internal environment for cellular function; understood how the cardiovascular system functions to deliver appropriate blood flows, pressures and nutrients to organs and tissues for optimal cellular function, and the role of the autonomic nervous system in co-ordinating and integrating cardiovascular function for homeostasis in the body; understood how the renal system functions to maintain the composition and amount of body fluids at optimal levels for cellular function; integrated the specific knowledge and insights gained in the study directed to the previous four objectives into a logical appreciation of the role in whole body physiology of the homeostatic systems of the body; developed an appreciation of the basis and manifestations of adaptations or dysfunction of these systems; developed an appreciation of the variability inherent in biological systems through laboratory exercises; promoted their abilities to organize and work in groups towards a common goal, through appropriate laboratory tasks and structured self-learning exercises; developed skills in laboratory techniques that are integral to the study of physiology; and developed skills in written communication through written reports on practicals and examination essays.
