The "cause" for something to happen is the

• response
• effect
• stimulus
• homeostasis

According to the model, what is a normal blood glucose (sugar) level?

• 270 mg/100mL

• 180 mg/100 mL

• 45 mg/100 mL

• 90 mg/100 mL

According to the model, what is the response to HIGH blood glucose (sugar)?

• Pancreas releases insulin into blood

• Pancreas releases glucagon into blood

According to the model, what is the response to LOW blood glucose (sugar)?

• Pancreas releases insulin into blood

• Pancreas releases glucagon into blood

The ability to maintain body temperature within a certain range is ...

• thermodynamics

• thermoregulation

• thermostat

• thermometer

Homeostasis

• allows for a wildly fluctuating internal environment
• is impossible in vertebrates
• is the maintenance of a relatively stable internal environment

• is the maintenance of a relatively stable external environment

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

When you exercise, what gas does your body NEED more of?

• Blood

• Carbon dioxide

• Hydrogen

• Oxygen

How does the body respond when more oxygen is required?

• Decreasing heart rate

• Increasing heart rate

• Decreasing blood pressure

• Increasing blood pressure
