What is homeostasis?
2. Slide
60 seconds
Homeostasis is the process of keeping bodily functions in balance, like temperature, respiration, and heart rate. The body's systems work together to maintain a stable internal environment, even when external conditions are changing. Our bodies use feedback systems to help maintain homeostasis, like the hypothalamus and the nervous system.

Question: How does the human body maintain homeostasis? Clues: • Homeostasis is the body's ability to maintain a stable internal environment. • The body's systems work together to regulate body temperature, pH levels, and other essential functions. • Hormones help to regulate the body's internal environment. In pairs: Select and solve one of the tasks: A. Choose a system of the human body and explain how it helps maintain homeostasis. B. Explain how the body can respond to external changes to maintain homeostasis.
