Example Input: 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. 
Example Output: digestive juices; digestive juice ,insulin ,glucagon
