Homeostasis

What is the best definition of homeostasis?

• Keeping a constant temperature

• Taking in oxygen and getting rid of carbon dioxide

• Getting rid of waste

• maintenance of a constant internal environment

What 2 organ systems control homeostasis?

• Endocrine system and nervous system

• Endocrine system and cardiovascular system

• Nervous system and respiratory system

• Nervous system and cardiovascular system

Why is it important to maintain a constant body temperature?

• to stop the multiplication of bacteria in the body

• so that we don't get cold

• to maintain the optimum temperature for enzymes

• so that we have enough energy to move
