Multiple Choice

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

Multiple Choice

What is involuntary contractions of voluntary muscles to warm up?

• Shivering
• Sweating
• Vasodilation
• Vasoconstriction

Multiple Choice

what is the function of control centre? 

• Process message and sends response message to effector
• Produce a respond to bring back factor value to normal condition
• Regulation of chemical and physical factors
• detects changes in stimulus and send message to control centre

Multiple Choice

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

Multiple Choice

Homeostasis in the human body is often maintained by a: 

• neutral feedback loop 
• solar feedback loop
• positive feedback loop
• negative feedback loop

Multiple Choice

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.

• False

• True

Multiple Choice

What is another word that can be used to describe "homeostasis"?

• STABLE
• EQUAL
• COMPLETE
• CORRECT

Multiple Choice

The term for maintaining internal temperature is: 

• Thermoregulation
• Thermometer
• Homeothermal
• Homeostasis

Multiple Choice

What is the evaporation of a liquid to cool the body?

• Shivering
• Sweating
• Vasodilation
• Vasoconstriction

Multiple Choice

Which body system controls the body to maintain homeostasis?

• excretory

• nervous

• circulatory

• skeletal
