Homeostasis and Body Regulation Concepts

What is homeostasis?

• The process of making energy from food.

• The process of changing the external environment.

• The process of increasing blood pressure.

• The process of maintaining a stable internal environment.

Who coined the term 'homeostasis'?

• Albert Einstein

• Walter Cannon

• Louis Pasteur

• Claude Bernard

What is the continual loop of disturbance and adjustment in homeostasis called?

• Positive feedback

• Thermoregulation

• Negative feedback

• Signal transduction

What is the modern model of homeostasis that involves organisms adapting to disruptions called?

• Thermoregulation

• Allostasis

What is the pH range of human blood maintained by homeostasis?

• 7.35 to 7.45

What happens when the human body becomes overheated?

• The body increases blood pressure.

• The body starts sweating.

• The body starts shivering.

• The body reduces blood circulation to the skin.

Which of the following is NOT a process controlled by homeostasis?

• They store minerals.

• They detect changes and report to the brain.

• They produce hormones.

What is the function of insulin in the context of allostasis?
