Subject Summary: Part IB Physiology
This course allows students to study systems physiology in detail and concentrates on mammals, in particular man. The course builds from knowledge of function at the cellular level to the complex operation of major body systems at the level of the whole organism. About 60% of the course is devoted to the study of all the major body systems. The remaining 40% takes an integrated approach to examine how these systems respond to various challenges from the everyday to the extreme.
The course begins by exploring the cardiovascular system, respiratory system, endocrine system, the kidney and body fluid homeostasis. The first part of the second term involves the study of reproductive physiology, starting with the male and female reproductive systems and following events from conception through implantation and embryonic development to parturition, and examining fetal, maternal, and neonatal physiology along the way. The second half of the second term looks at digestion, absorption, nutrition and body weight regulation. In the Easter term we examine the response of the body to exercise, including the effects of training and detraining and the limitations on performance, and we also look at the responses of the body to extreme conditions presented by life at high altitude, in the Arctic, the desert and during space flight.
Practical work is largely designed to allow students to study their own physiology. Examples include examining the effects of exercise on cardiac output and oxygen consumption, the effects of eating chocolate on blood glucose and respiratory quotient, and the pharmacological effects of drugs on isolated intestinal muscle. You will also be introduced to the principles of histology, including working with some of the latest, computer-based packages. Two practical classes in the second term are given over to the assessment of fitness and the effects of training in selected individuals.
Part IB Physiology builds on topics introduced in Part IA Physiology of Organisms, but it is not essential to have taken this course to read Part IB Physiology. As well as being interesting in its own right (even to predominantly physical scientists), Physiology is well suited to accompany many other Part IB courses in the life sciences, including Biochemistry and Molecular Biology, Cell and Developmental Biology, Experimental Psychology, Neurobiology, Pathology, and Pharmacology.
Programme Specification: Part IB Physiology
This course is taught by the Department of Physiology, Development, and Neuroscience.
- to provide a course of study in mammalian, principally human, physiology, building on knowledge of basic physiological principles, covering many topics incompletely or not taught in the Part IA Physiology of Organisms course;
- to prepare students for a number of Part II Natural Science courses, principally Physiology, Development and Neuroscience, but also Pharmacology, Pathology and Zoology, among others.
At the end of the course students should:
- have an enhanced knowledge and appreciation of mammalian physiology;
- have gained knowledge of a number of important physiological systems including the cardio-respiratory, renal and reproductive systems;
- be able to recognise and identify the principle tissue structures in those systems;
- be able to analyse and extrapolate from their knowledge of the separate systems to discuss physiological responses to challenges such as exercise, fasting and ascent of altitude.
Teaching and Learning Methods
These include lectures, supervisions and practical classes.
Assessment for this course is through:
- an unseen written examination based on the content of the lecture course (for aims 1-2 and learning outcomes 1-4)
- an unseen written examination based on practical work conducted throughout the year (for aims 1-2 and learning outcomes 1-4)
- a practical examination involving the interpretation and identification of slides, micrographs and experimental records (for aims 1-2 and learning outcomes 1-4)
Courses of Preparation
Essential: either NST Part IA Physiology of Organisms or NST Part IA Biology of Cells.
Recommended: A Levels in Biology, Chemistry, and/or Physics.
