Homeostasis Refresh

The body's ability to maintain relatively stable internal conditions even though the outside world is continuously changing IS CALLED:

• Effector

• Homeostasis

• Insulin

• Stimulus

True or false: In order to maintain homeostasis, our body needs to detect and respond to changes.

• true

• false

a sensor that monitors and detects changes IS CALLED...

• Effector

• Receptor

• Stimuli

• Control Center

A change to the system (usually an increase or decrease in whatever is being monitored) IS CALLED....

• Receptor

• Control Center

• Effector

• Stimuli

• Analyzes the information that is received and determines the appropriate response or the appropriate structure to correct the change.

• Effector

• Receptor

• Control Center

• Stimuli

What makes the necessary changes happen in order to STABILIZE a problem IS CALLED...

• Effector

• Stimuli

• Receptor

• Control Center

NGSS.HS-LS1-3

• The process that increases the intensity of the stimulus to allow conditions to push beyond the normal range (very rare in the human body, example is childbirth)

• Negative Feedback

• Homeostasis

• Positive feedback

• pH

• Reduces the intensity of the stimulus to allow conditions to return to the normal range and keep conditions within a specific range. We saw this in the pH lab!

• Negative feedback

• Cell Membrane

• Effector

• Receptor

Put the steps of the negative feedback loop in the correct order

• Control Center

• Back to stable conditions

• Stimulus/change happens

• Effector

• Receptor
