Module 8: Non-infectious Disease and Disorders    Revision 1  Revision 2   Revision 3


Inquiry question: How is an organism’s internal environment maintained in response to a changing external environment?


      construct and interpret negative feedback loops that show homeostasis by using a range of sources, including but not limited to:

      temperature glucose

      investigate the various mechanisms used by organisms to maintain their internal environment within tolerance limits, including:

      trends and patterns in behavioural, structural and physiological adaptations in endotherms that assist in maintaining homeostasis

      internal coordination systems that allow homeostasis to be maintained, including hormones and neural pathways

      mechanisms in plants that allow water balance to be maintained

Causes and Effects

Inquiry Do non-infectious diseases cause more deaths than infectious diseases?:question


      investigate the causes and effects of non-infectious diseases in humans, including but not limited to:

      genetic diseases

      diseases caused by environmental exposure

      nutritional diseases


      collect and represent data to show the incidence, prevalence and mortality rates of non-infectious diseases, for example:

      nutritional diseases

      diseases caused by environmental exposure


Inquiry question: Why are epidemiological studies used?


      analyse patterns of non-infectious diseases in populations, including their incidence and prevalence, including but not limited to:

      nutritional diseases

      diseases caused by environmental exposure

      investigate the treatment/management, and possible future directions for further research, of a non-infectious disease using an example from one of the non-infectious diseases categories listed above

      evaluate the method used in an example of an epidemiological study

      evaluate, using examples, the benefits of engaging in an epidemiological study


Inquiry question: prevented? be How can non-infectious diseases


      use secondary sources to evaluate the effectiveness of current disease-prevention methods and develop strategies for the prevention of a non-infectious disease, including but not limited to:

      educational programs and campaigns

      genetic engineering


Technologies and Disorders

Inquiry question used to assist people who experience disorders? be: How can technologies


      explain a range of causes of disorders by investigating the structures and functions of the relevant organs, for example:

      hearing loss

      visual disorders

      loss of kidney function

      investigate technologies that are used to assist with the effects of a disorder, including but not limited to:

       hearing loss: cochlear implants, bone conduction implants, hearing aids

      visual disorders: spectacles, laser surgery

      loss of kidney function: dialysis

      evaluate the effectiveness of a technology that is used to manage and assist with the effects of a disorder
