Homeostasis

Identify the STIMULUS.

• temperature change is noticed

• person begins to sweat

• body temperature decreases

• person begins to exercise

Identify the RESPONSE. Scenario: A person begins to exercise which causes their body temperature to increase. The temperature change is noticed and the person begins to sweat and their body temperature decreases.

• temperature change is noticed

• body temperature increases so the person begins to sweat

• body temperature decreases

• person begins to exercise

Homeostasis in the human body is often maintained by a: 

• the brain only

• solar feedback loop

• the muscles

• negative feedback loop

Your body is too hot. What senses your body temperature?

• nerve cells

• sweat cells

• blood cells

• muscle cells

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

What describes a lack of water in the blood?

• Dehydration

• Rehydration

• Hydration

• Concentrated

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

When CO2 levels become too high in our blood, we begin to breathe faster. In this example, our diaphragm and intercostal muscles are

• the stimuli

• the response

• the effectors

• the neurons
