Topic One

How does the body stay healthy?

In this topic, you will explore how the body maintains its internal balance (homeostasis) to stay healthy and investigate diseases, gaining a deeper understanding of the difference between non-infectious and infectious diseases.

LEARNING INTENTIONS

  • Define homeostasis, negative feedback loop, and infectious disease.
  • Explain how the body maintains homeostasis through real-life examples.
  • Recognise the organisms, pathogens, or germs that cause infectious disease.

SUCCESS CRITERIA

  • Provide real-life or creative examples of how the body regulates homeostasis.
  • Differentiate between health and disease with appropriate terms.
  • Identify different pathogens that disrupt the body’s balance.

An interview with Prof Peter Doherty

Nobel Prize Winner

 

In this video, Prof. Peter Doherty, a Nobel Prize winner, explains how pathogens (germs) can cause diseases and disrupt the body’s natural balance, called homeostasis. The video will help you understand how infections challenge your body’s ability to stay stable and what happens when your body can’t maintain that balance. By watching this, you’ll learn how the body works to stay healthy, even when it’s under attack by harmful germs.
