Unit description Unit description
This unit considers the maintenance of body homeostasis. We investigate the cardiovascular system including an examination of the electrical and mechanical functions of the heart, its interaction with the blood vessels, and the hormones and the autonomic nervous system that control heart function. Next we study the role of the renal system in the control of the chemical composition of the body, water balance and body fluid volume. An overview of the respiratory and gastrointestinal systems will follow. Practical classes involve measuring physiological parameters such as blood pressure and electrical conduction through the heart (the ECG) in humans.

Important Academic Dates

Information about important academic dates including deadlines for withdrawing from units are available at http://students.mq.edu.au/student_admin/enrolmentguide/academicdates/

Learning Outcomes

  1. Explain how the cardiovascular, renal and respiratory systems contribute to the maintenance of homeostasis
  2. Relate specific structural features of organs to essential system functions
  3. Interpret physiological processes using equations of physical, chemical, and electrical properties
  4. Identify situations in which organ systems interact to produce a co-ordinated response
  5. Perform experiments safely with human subjects and accurately collect data, following Macquarie University Human Research Ethics Committee sanctioned protocols
  6. Analyse data and recognise the implications of experimental results

General Assessment Information

A hurdle requirement is an activity for which a minimum level of performance or participation is a condition of passing a unit. The hurdle requirement in BIOL247 this year is that you must attend six out of the 10 practical sessions (ie 8 practicals,  the mid-semester test and the revision tutorial). If you miss part of an on-campus session due to illness or other unforeseen circumstances you must submit a Disruption to Studies request

Delivery and Resources

Unit Schedule

There will be two lectures each week on Wednesday at 1 pm and Thursday 12 noon. Both lectures are of one hour duration and will be held in the Lotus Theatre (W6D 27WW). The lecture audio and graphics will also be available through ECHO on the ILearn site.

External students will attend practical classes on 26th & 27th of August and the 18th & 19th of September. The classes start promptly at 9.00 am and will be held in F7B 102, 105 and 110. You will be expected to have covered all the information in the preceding lectures and to have read through the description of the practical prior to the practical sessions.

You will also find online lectures in ECHO on an “Introduction to Neurophysiology” and the “Autonomic Nervous System”. The background information contained in these lectures is required for understanding of concepts introduced in BIOL247 so it is essential that all students who have not completed BIOL257 study these lectures in week one. These lectures will also be a helpful revision tool for students who have completed BIOL257. 

Unit material and Textbooks

The textbook for this unit is “Principals of Human Physiology” by Cindy L Stanfield, published by Pearson. You can subscribe to the new digital version (6th addition) at

http://www.pearson.com.au/9781292156491

and you do not need MasteringA&P.

An alternative is “Physiology” by Jake Mann and David Marples published by JP medical publishers. This book is one of the Eureka series and is more concise than Stanfield but still covers the content of BIOL247.  Other physiological texts of a similar standard may also be suitable.

iLearn

Your iLearn site will contain the unit outline, lecture audio and graphics, the text of the lectures, a link to ECHO 360 practical notes, announcements and discussion areas, and other information to help you complete the unit. Later, quizzes and assignment marks will be added. Please check this site regularly. You should also check your university email regularly for important announcements.
