A detailed examination of the physiology and pathophysiology of the cardiac, vascular and respiratory systems. The course focuses on integration of physiological mechanisms at the molecular, cellular and systems levels.


This course is an advanced course in cardiovascular and respiratory physiology. The information learned in BPK205 is the starting point for discussions about these systems. Students are encouraged to review their BPK205 notes and text (Human Physiology by Silverthorn) prior to the start of the BPK305 lectures.

Students who miss examinations due to exceptional circumstances (such as serious illness or compassionate reasons) are required to obtain a physician's certificate, whereby the physician states that you were unable to write your midterm or final on the set date due to a medical condition beyond your control, or other supporting documents in order to obtain consideration in the course. Such documents must be filed with the Department Chair (via the Biomedical Physiology and Kinesiology office) or Registrar within four calendar days of the date on which the examination was to have been written. Exceptional circumstances must be approved by the Undergraduate Program Committee in order for a student to receive consideration. Students must check the examination schedule when making course selections. Students are reminded that final examinations may be scheduled at any time during the examination period and that students should avoid making travel or employment arrangements for this period. In the event of a missed midterm or final examination the instructors reserve the right to give an oral examination of the material. Approximate midterm dates are provided, but may be subject to change.


Academic honesty is a condition of continued membership in the University community. Academic dishonesty, including plagiarism or any other form of cheating is subject to serious academic penalty. The University codes of student conduct and academic honesty are contained in policies T10.01 and T10.02 which are available in the Course Timetable and on the Web via http://www.reg.sfu.ca.



Physiology, Berne, RM, Levy, Koeppen & Stanton, Mosby, (Updated) 6th edition OR

Medical Physiology, Boron and Boulpaep, Saunders (Updated) 2nd edition

Having access to one of these textbooks is HIGHLY recommended for this course.

Department Undergraduate Notes:

It is the responsibility of the student to keep their BPK course outlines if they plan on furthering their education.

Registrar Notes:


SFU’s Academic Integrity web site http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating.  Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the University community.  Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University. http://www.sfu.ca/policies/gazette/student/s10-01.html


Teaching at SFU in spring 2022 will involve primarily in-person instruction, with safety plans in place.  Some courses will still be offered through remote methods, and if so, this will be clearly identified in the schedule of classes.  You will also know at enrollment whether remote course components will be “live” (synchronous) or at your own pace (asynchronous).

Enrolling in a course acknowledges that you are able to attend in whatever format is required.  You should not enroll in a course that is in-person if you are not able to return to campus, and should be aware that remote study may entail different modes of learning, interaction with your instructor, and ways of getting feedback on your work than may be the case for in-person classes.

Students with hidden or visible disabilities who may need class or exam accommodations, including in the context of remote learning, are advised to register with the SFU Centre for Accessible Learning (caladmin@sfu.ca or 778-782-3112) as early as possible in order to prepare for the spring 2022 term.
