Homeostasis Quiz

What is the purpose of homeostatic mechanisms in the human body?

• To prevent the body from functioning normally

• To disrupt the normal range of values

• To cause fluctuations in internal conditions

• To maintain stable internal conditions

What is the set point in homeostasis?

• A fluctuating value

• An average normal value

• A value that causes disease

• A value that prevents normal function

What is the main function of negative feedback mechanisms?

• To decrease any deviation from the set point

• To increase any deviation from the set point

• To maintain variation within a normal range

• To prevent the body from achieving homeostasis

What is the purpose of positive feedback mechanisms?

• To prevent the body from achieving homeostasis

• To decrease the response to an initial stimulus

• To maintain variation within a normal range

• To further stimulate the response to an initial stimulus

What are the three components of most negative-feedback mechanisms?

• Receptor, control center, effector

• Receptor, processor, output

• Sensor, processor, output
