BIOS2170: Body Systems and Human Performance

Semester 1, 2026 [Normal day] - Camperdown/Darlington, Sydney

This unit examines the cardiovascular, respiratory, and urinary systems, focusing on their roles in human movement and performance. It builds on core concepts of anatomy, histology, physiology, and pathophysiology, including strategies for maintaining acid-base balance in a range of different scenarios. Students participate in hands-on practical classes, including use of human cadavers, and perform common cardiovascular and respiratory function tests. Tutorial workshops apply these concepts to real-world applications, such as evaluating the effects of drugs on sports performance, comparing dehydration and overhydration, and investigating cardio-respiratory adaptations to extreme environments like deep-sea diving and mountaineering. On completion of the unit, students will be able to synthesize knowledge across topics, demonstrating an integrated understanding of the homeostatic adaptations crucial to human movement and performance.

Details are provided in the Canvas site and your result will be recorded in your Marks page. It is important that you actively engage with this task so that the University can support you to be successful in this unit.

Assessment summary

  • On-line quizzes: The final mark and will include the 5 best performances. Each quiz will be available online for a limited time. You will be advised when quizzes are available and must complete the quizzes within the period of availability.
  • Feedback questions: Feedback questions will be made available weekly. You must submit your answers by email. You must complete 5 weeks of feedback questions. Completion of the other week’s feedback questions is optional.
  • In-semester assessment: This activity will cover introduction to basic biology and cardiovascular system (anatomy, physiology and pathophysiology).
  • Final assessment: This open book exam will cover the material that was not covered in the mid-semester exam. Calculators are not permitted in examinations; assessments have been modified so that calculators are not required.

Detailed information for each assessment can be found on Canvas.

Use of generative artificial intelligence (AI)

You can use generative AI tools for open assessments. Restrictions on AI use apply to secure, supervised assessments used to confirm if students have met specific learning outcomes.

Refer to the assessment table above to see if AI is allowed, for assessments in this unit and check Canvas for full instructions on assessment tasks and AI use.

If you use AI, you must always acknowledge it. Misusing AI may lead to a breach of the Academic Integrity Policy.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The University expects students to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

Our website provides information on academic integrity and the resources available to all students. This includes advice on how to avoid common breaches of academic integrity. Ensure that you have completed the Academic Honesty Education Module (AHEM) which is mandatory for all commencing coursework students

Penalties for serious breaches can significantly impact your studies and your career after graduation. It is important that you speak with your unit coordinator if you need help with completing assessments.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Support for students

The Support for Students Policy reflects the University’s commitment to supporting students in their academic journey and making the University safe for students. It is important that you read and understand this policy so that you are familiar with the range of support services available to you and understand how to engage with them.

The University uses email as its primary source of communication with students who need support under the Support for Students Policy. Make sure you check your University email regularly and respond to any communications received from the University.

Attendance and class requirements

  • The University of Sydney Coursework Policy 2014 states: 
    55 (2) A student enrolled in a unit of study must comply with the requirements set out in the faculty resolutions, award course resolutions or unit of study outline about undertaking the unit of study, including on matters such as: (a) attendance at and participation in lectures, seminars and tutorials; and (b) participation in practical work. The Faculty of Medicine and Health resolutions states: 7(1) Students are required to attend at the correct time and place of any formal or informal examinations. Non-attendance on any grounds insufficient to claim special consideration or special arrangement will result in the forfeiture of marks associated with the assessment. Participation in a minimum number of assessment items may be included in the requirements specified for a unit of study.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.
