Description
This unit explores the human gas exchange system, focusing on the impact of exercise, asthma, smoking, recreational drugs, and the differences between infectious and non-infectious diseases. It emphasises understanding scientific methods, evidence, risk evaluation, and peer review importance.
This unit builds on pupils’ prior learning from Diet and exercise, where they explored how lifestyle choices impact overall health and body systems. It deepens their understanding by examining the role of disease and drugs, focusing on how different conditions affect the body and the use of medications. This prepares pupils for the next unit, Health and disease, where they will apply their knowledge to explore the interactions between communicable and non-communicable diseases, lifestyle factors, and prevention strategies, reinforcing the link between health management and disease prevention.
