• To keep the body in a state of imbalance

• To maintain a stable internal environment

• To decrease blood glucose levels

How does the body respond when it is too hot?

• By dilating blood vessels and sweating

• By shivering to generate heat

What hormone is released when blood sugar is too high?

• Adrenaline

• Glucagon

• Thyroxine

• Insulin

What is an example of positive feedback in the body?

• Shivering to warm up

• Childbirth contractions

• Regulation of blood glucose

• Sweating to cool down

Why is understanding feedback systems important?

• To understand problems like type 1 diabetes

• To decrease blood glucose levels

• To increase body temperature

• To ignore body processes
