If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

When you are cold, you shiver and your blood vessels contract, which warms you up. When you are hot, you sweat and your blood vessels expand, which cools you down.  

• Positive Feedback Response
• Negative Feedback Loop

In this body temperature feedback loop, predict what would happen if cooling mechanisms were NOT activated?

• The body would not warm up.

• The body would not cool down.

• Your body would get colder and colder.

• Your body would release lots of heat.

What is the difference between what will happen if their is too much Glucose or too little Glucose? SELECT ALL THAT APPLY

• With too much Glucose, Insulin is released. With too little Glucose, Glucagon is released.

• With too much Glucose, the pancreas produces insulin. With too little Glucose, the pancreas produces glucagon.

• With too much Glucose, Glucagon is released. With too little Glucose, Insulin is released.

• There is no difference.
