Homeostasis and Regulation Review

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

• Kidneys

• Liver

• Pancreas

• Appendix

What is the point of a feedback loop?

• To provide the body with more energy

• To provide the body with more food

• To make sure the conditions in the body are always changing

• To make sure the conditions in the body remain stable
