Synopsis

The unit examines the biological determinants of the major non-communicable diseases that are common global causes of death and disability. Students will be encouraged to integrate knowledge of physiological factors, genetic factors and lifestyle choices to explain health and disease; and to appreciate that knowledge of the biological determinants of disease can be applied to the prevention and control of disease. Case studies will provide the opportunity to develop critical reasoning skills, self-learning and literacy skills necessary for understanding the biological bases of health and disease.

Outcomes

Upon successful completion of this unit, students should be able to:

Discuss ways in which under-nutrition and over-nutrition contribute to the global burden of disease;
Explain the basics of human genetics with reference to examples of human diseases that are caused by chromosomal, single gene or polygenic defects;
Describe the structure of human cells and their functions in adaptive and non-adaptive responses to harmful environmental stimuli;
Explain the biological basis of cardiovascular disease and its important risk factors that contribute to the high global prevalence of heart attack and stroke;
Apply knowledge of the digestive tract, genetics, and dietary factors to explain the nature and occurrence of colorectal cancer;
Explain how the function of gas exchange can be disrupted in obstructive respiratory disease and the health consequences in chronic conditions; and
Explain the biological bases of selected global health problems and discuss possible approaches towards their prevention and control.
