Course Brief

Unit Aim
This unit aims to provide learners with basic grounding in areas of science which are especially relevant to public health. It will help to ensure that all learners have an understanding of how our bodies work (anatomy, physiology and biochemistry) and how they may become infected (microbiology and parasitology). By studying environmental science, learners will appreciate the importance of the environment to human health. The study of health economics will raise awareness of the impact of personal, local and national finances on health and access to healthcare.


Unit Overview
It introduces learners to the biological sciences (anatomy, physiology, biochemistry, microbiology and parasitology) which are most relevant to public health. Anatomy and physiology address the structure and function of the main body systems. Biochemistry enables an understanding of metabolism and neurotransmitter activity. Environmental science forms an important part of this unit as it broadens the learners’ view of the factors which impact on public health.


Learning Outcomes
After successfully completing this unit, the learner will:
1. Describe the structure (anatomy) and functions (physiology) of the main body systems
2. Explain how biochemistry can help us to understand body processes
3. Explain how microbes enter the body and reproduce in terms of microbiology and parasitology
4. Analyse the impact of environmental issues on health
5. Assess the impact of finances on the health and care of individuals and populations
