Homeostasis is the process of keeping the environment inside the bodoy fairly constant.

Aspects of the internal environment that the body needs to regulate:

• core body temp.
• pH and body fluids
• concentration of gluscose in the blood
• concentration of o2 and co2 in the blood and other body fluids
• blood pressure
• concentration of metabolic wastes

Feedback system/Feedback loop, is a situation where the response to a stimulus modifies the stimulus.

Negative Feedback=

In homeostatic mechanisms the response has the effect of reducing or eliminating the stimulus that caused it.

Positive Feedback=

The response to a stimulus reinforces and intensifies the stimulus-greater response. cannot result in homeostasis and this is an important process that must be completed quickly!

The formation of glycogen from other carbohydrates, especially glucose

• Stimulated by the pancreatic hormone- insulin 
• Insulin= hormone, secreted by the pancreas, that decreases blood sugar level

Breakdown of glycogen to glucose

• Occurs in the liver
• Gluscose is formed and then released into the blood, and the blood sugar level rises.
