Unit 4 Quiz

To increase the body's overall size and mass.

To generate energy for cellular respiration.

To maintain a relatively stable internal environment despite changes in the external environment.

To produce specialized cells for growth and repair.

It amplifies an initial stimulus to drive a process to completion.

It works to counteract an initial change to return a condition to its normal range.

It is the body's first response to any external threat or change.

It is the only type of feedback loop that involves hormones.

Metabolic feedback loop

Positive feedback loop

Negative feedback loop

Internal feedback loop

Blood sugar regulation

Childbirth contractions

Body temperature regulation

Blood pressure control

A baby's head pressing on the cervix during childbirth, which causes stronger contractions.

Your blood pressure increasing, which causes the heart rate to slow down.

The release of clotting factors after a cut, leading to more clotting factors being released.

A rise in body temperature causing shivering to generate more heat.

It works to bring a physiological condition back to its set point.

It slows down a process to prevent it from overshooting its target.

It amplifies an initial stimulus to drive a process to completion.

It is used to maintain the body's core temperature.

The body's response is to counteract the initial change.

It is primarily used to maintain a constant internal temperature.

The body's response is to amplify the initial change.

It is the most common type of feedback loop in the human body.

Blood sugar levels dropping, which causes the liver to release glucose.

Your body's core temperature rising, which triggers sweating to cool you down.

The release of clotting factors after a cut, leading to more clotting factors being released.

The feeling of thirst, which causes you to drink water and restore fluid balance.

The body's response would hinder the treatment by causing the patient to sweat, working against the warming efforts.

The body's response would hinder the treatment by causing blood vessels to dilate, losing more heat.

The body's response would aid the treatment by causing shivering, which generates internal heat.

The body's response would have no effect on the treatment, as it only responds to internal changes.

Positive feedback loops maintain homeostasis, while negative feedback loops disrupt it.

Positive feedback loops amplify a change, while negative feedback loops counteract a change.

Positive feedback loops are more common in the body than negative feedback loops.

Positive feedback loops require a stimulus, but negative feedback loops do not.
