Homeostatic Feedback Loops

Select 2 statements that describe the negative feedback loop:

• It occurs more frequently/often

• It reverses the original stimulus to bring the body in balance

• It enhances/strengthens the original stimulus to bring the body in balance

• It doesn't occur very often

Blood pressure, body temperature, and sugar levels would be monitored by this type of feedback loop:

• Negative

• Positive

• Receptor

• Effector

Select 2 statements that describe the positive feedback loop:

• It reverses the original stimulus to bring the body in balance

• It doesn't occur very often

• It occurs more fequently/often

• It enhances/strengthens the original stimulus to bring the body in balance

This term means: The body internal environment is in a state of stability and balance.

• Feedback loop

• Life processes

• Physiological limit

• Homeostasis

NGSS.HS-LS1-3

The feedback player/component determines all physiological limits, and decides what responses should be

• Nervous System

• Receptor

• Control Center

• Effector

Tags

NGSS.HS-LS1-3

The control center tells this player/component what needs to be done in order to bring the body back to homeostasis.

• Brain

• Receptor

• Sensor

• Effector
