Pupils will learn about human and plant defences against pathogens, the role of white blood cells in the human immune system, and the use of vaccination to protect against communicable diseases.

Pupils learned about some common non-infectious diseases, factors that increase the risk of developing lifestyle diseases and steps we can take to help prevent them, including the impacts of smoking on the human body, and asthma and its risk factors.

This unit explores health and disease, including communicable and non-communicable types and their interactions. It examines lifestyle impacts, disease spread, evaluates cardiovascular treatments, and highlights the importance of risk evaluation, peer review, and effective communication of results.
