Chapter 7: The Human - As a biological system

Abstract

To be able to provide appropriate advice on the effects of hazards on workers’ health and to competently assess the potential impacts of changes in the workplace, the generalist OHS professional requires a working knowledge of the physiology of the human body. After a brief history of the association of workplace exposures with worker health and wellbeing, this chapter presents an overview of the biological systems of the human body. Two case studies – featuring the nervous system and the integumentary system – provide examples of the application of physiological knowledge in the OHS context.

Keywords: nervous system, respiratory system, endocrine system, reproductive system, digestive system, skin, musculoskeletal

The OHS Body of Knowledge takes a conceptual approach which enables it to be applied in different contexts and frameworks.

To optimise its value for education and professional development learning outcomes have been developed for each technical chapter in the Body of Knowledge.

The learning outcomes as described give an indication of what should be the capabilities of an OHS professional; it is up to those developing OHS education programs, OHS professionals planning their CPD or recruiters or employers selecting or developing people for the OHS function to consider the required breadth vs. depth .

Please read the section on using the learning outcomes before delving into the leaning outcomes of the individual chapters.

The numbers against each learning outcome refer to the chapter number of the BOK download page. No learning outcomes have been developed for the chapters considered introductory or underpinning knowledge (that is chapters 1, 2, 3, 4, 5, 6, 7, 1, .13, 14, 15.)
