Adv Bio Homeostasis

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

• To decrease bone density over time

• To ensure rapid growth of cells

• To maintain consistent internal conditions

• To increase blood pressure during stress

What metaphor is used to explain the concept of homeostasis?

• A car on a highway

• Balancing a ruler on a finger

• A boat in a stormy sea

• A tree bending in the wind

What is the first step in the homeostasis process?

• Correction

• Detection

• Integration

• Comparison

What does the body compare the current condition to during homeostasis?

• An external condition

• The set point

• A future condition

• A previous condition

What role does the brain play in the homeostasis process?

• Sensor

• Effector

• Set point

• Integrator

Which of the following is a sensor for blood pressure in the body?

• The spleen

• The liver

• The aorta

• The pancreas

What is the set point for normal human body temperature in Celsius?

• 35 degrees

• 37 degrees

• 42 degrees

• 40 degrees

How does the body respond when the internal temperature is too high?

• By shivering

• By sweating

• By sleeping

• By increasing heart rate

What mechanism does the body use to lower its temperature?

• Dilating blood vessels

• Increasing muscle activity

• Constricting blood vessels

• Decreasing sweat production

In this situation, the role of the brain is the

• set point

• sensor

• integrator

• effector
