Understanding Homeostasis

What is the primary function of homeostasis in the human body?

• To increase the body's nutrient levels

• To change the body's temperature frequently

• To keep the internal environment stable

• To maintain a constant external environment

Which of the following is an example of homeostasis in action?

• The body temperature dropping to 90°F

• The body temperature rising to 105°F

• The body temperature remaining around 98.6°F

• The body temperature fluctuating wildly

What does the term 'set point' refer to in the context of homeostasis?

• A point where the body stops functioning

• A normal range the body tries to stay within

• A level of nutrients that is always constant

• A fixed temperature the body must maintain

How does the body respond to weight gain in terms of blood pressure?

• It keeps the blood pressure set point unchanged

• It eliminates the blood pressure set point

• It increases the blood pressure set point

• It decreases the blood pressure set point

Why is the ability to maintain homeostasis crucial for life?

• It ensures stable internal conditions

• It allows the body to change constantly

• It stops the body from adapting to changes

• It prevents the body from using energy

In the fish tank model, what does the water represent?

• The internal environment

• The external environment

• The skin

• The cells

In the fish tank analogy, what does the air pump symbolize?

• The muscles

• The kidneys

• The digestive system

• The lungs

What role does the heater play in the fish tank model?

• It represents the skin

• It represents the muscles

• It represents the kidneys

• It represents the lungs

What is the purpose of the feeder in the fish tank model?

• To represent the lungs

• To represent the kidneys

• To represent the skin

• To represent the digestive system

What is emphasized about the fish tank model in the conclusion?

• It is the only model for homeostasis

• It is not useful for understanding homeostasis

• It is a simplified representation

• It covers all aspects of homeostasis
