AQA GCSE Biology - B3 Infection and Response: Health and Disease

Vocabulary flashcards covering health, communicable and non-communicable diseases, disease interactions, and risk factors from AQA GCSE Biology B3 Lesson 1.

Health

The state of physical and mental well-being and not just the absence of disease.

Communicable diseases

Diseases caused by pathogens such as bacteria or viruses that can be transmitted between individuals.

Non-communicable diseases

Diseases that are not infectious and cannot be passed from person to person (e.g. cancer, diabetes).

HPV

A virus infection that can trigger cancer.

Risk factor

Something that increases the likelihood of a person developing a disease.

Biological risk factors

Factors that increase disease risk, including inherited genetic disorders, age, and gender.

Lifestyle risk factors

Factors that increase disease risk, including poor diet, lack of exercise, smoking, and excessive alcohol consumption.

Immune system defects

Flaws in the immune system that make the body less able to destroy pathogens, increasing the chance of catching infectious diseases and making infections more severe.

Uncontrolled cell division

A process that can be caused by certain viruses, leading to the development of cancer.
