Homeostasis Virtual Lab

With low oxygen levels, your breathing rate will increase. When your oxygen levels rise, what is the appropriate response?

• stop breathing

• increase heart rate

• keep breathing rate high

• return breathing rate to baseline

Homeostasis is defined as:

• The process of maintaining a stable internal environment

• The process of maintaining a stable environment

• Keeping your temperature at a set point

• Receptors sensing changes in your body

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

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

What type of feedback loop is shown?

• Positive

• Neutral

• Negative

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

Negative Feedback Loops:

• amplify processes

• prevent small changes from getting larger

• are initiated during childbirth

• are found only in plants

In a virtual lab simulation, if the external temperature drops, what homeostatic response might you observe in a warm-blooded animal?

• Increased sweating

• Decreased heart rate

• Shivering to generate heat

• Dilated blood vessels

Which of the following is an example of a negative feedback mechanism in homeostasis?

• Blood clotting

• Childbirth contractions

• Regulation of blood glucose levels

• Nerve signal transmission
