Unit Summary
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.
Lesson Summary
You will learn to describe communicable and non-communicable diseases, including causes and risk factors.
Key Notes
- The good health of humans, other animals and plants can be compromised by diseases.
- Communicable diseases are spread by pathogens, including some bacteria, viruses, fungi and protists.
- Non-communicable diseases cannot be spread between organisms; they are caused by lifestyle and environmental factors.
- Lifestyle factors (e.g. hygiene, diet) affect the chances of developing communicable and non-communicable diseases.
Vocabulary To Learn
- communicable disease: A disease, caused by a pathogen, that can be spread from person to person through direct or indirect contact.
- non-communicable disease: A disease that cannot be spread from person to person.
- disease: A persistent deviation from a person's normal appearance, body function or behaviour.
Common Mistakes To Avoid
- A person is either healthy or unhealthy.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
The good health of humans, other animals and plants can be compromised by diseases. Communicable diseases are spread by pathogens, including some bacteria, viruses, fungi and protists.
2. Define this scientific word and use it in context. 'communicable disease'
A disease, caused by a pathogen, that can be spread from person to person through direct or indirect contact. Include the word in a full scientific explanation, not as a single label.
