Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• maintains a stable internal environment

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

what is the function of integumentary system to control body temperature high?

• arterioles in the epidermis dilate so that more blood flow to the skin
• produce hormones to reduce the metabolic rate
• sweat glands in the skin produce more sweat and hair erector mucles relax to let the hair lie down
• detect the temperature and send to nerve impulses to the brain

The tendency of an organism to maintain a balanced state in order to stay healthy.

• Stimuli
• Response
• Tropism
• Homestasis

Negative Feedback Loops:

• amplify processes
• prevent small changes from getting larger
• are initiated during childbirth
• are found only in plants

Which part of the feedback loop is a body part that makes a change to bring the system back to homeostasis?

• Effector

• control center

• response

• receptor

What detects that the system is outside of homeostasis and adjustments need to be made?

• effector

• response

• control center

• stimulus
