,ZOO 2541: Animal Physiology About This Module
1. Aims of this module
The aim of this module is to provide you with an overview of the study area of animal physiology and to
introduce you to the principles of this field that underlie all animals. It provides a comprehensive outline
of physiological systems in a well-organized and concise manner by moving between description of general
principles of physiology and specific examples of these principles from a variety of animal species. It starts
with essential chemical and physical laws that govern physiological processes in animals (unifying themes
in physiology). These provide a foundation to understand the breadth of physiology. The module illustrates
how the major physiological systems function and integrate to sustain the lives of animals.
2. Learning outcomes
- Develop critical thinking skills and be able to apply physiological concepts and principles at the basic and
applied levels.
- Develop a working knowledge of the major physiological systems and be able to associate anatomical areas
with their specific function.
- Develop an understanding of the role of evolutionary processes (e.g. natural selection) in driving the
organization of physiological systems.
- Understand important physiological challenges animals face, how those challenges vary in relation to the
animals’ environment, and the processes by which animals deal with these challenges.
- Identify and describe structural differences of major physiological systems that characterize different
taxonomic groups of animals.
- Relate physiological processes, from the biochemical to the system level, to the function of the entire
organism in its environment.
- Learn to properly and safely use animals and modern laboratory equipment to conduct physiological
research
