According to the model, what is the response to HIGH blood glucose (sugar)?

• Pancreas releases insulin into blood

• Pancreas releases glucagon into blood

According to the model, what would happen if the pancreas did NOT detect rising blood glucose (sugar) level?

• Blood sugar would return to normal

• Most body cells would take up more glucose

• Blood sugar would stay above normal

• The liver would get the message to store glucose as glycogen

Homeostasis

• allows for a wildly fluctuating internal environment
• is impossible in vertebrates
• is the maintenance of a relatively stable internal environment

• is the maintenance of a relatively stable external environment
