The two types of feedback systems that help organisms maintain homeostasis are:

• positive and negative 
• receptor and effector
• static and dynamic
• minor and major

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels. 

• Positive Feedback Response
• Negative Feedback Loop

Negative Feedback Loops:

• amplify processes
• prevent small changes from getting larger
• are initiated during childbirth
• are found only in plants

• glucose
• glucagon
• insulin
• glycogen

• internal conditions remain stable

• external conditions remain stable
