Fans blow air onto the evaporator's coils. The refrigerant within the coils absorbs the heat. The refrigerant changes from a liquid to a gas. The compressor compresses the gas, increasing the pressure. The hot, pressurized gas moves to the condenser. The gas condenses in the condenser and becomes a liquid again. Heat is radiated away from the condenser. The cooled liquid is returned to the evaporator.

Over 99% of the exocrine pancreas cells produce digestive juices. They secrete digestive juice "externally" into the small intestine. There are enzymes for breaking down fats, proteins , and carbohydrates. Digestive juices flows from the pancreas through an excretory duct into the small intestine. When the blood sugar levels rise, as they might after a meal, insulin is released. When blood sugar levels are too low, the pancreas releases glucagon into the bloodstream.
