A healthy pancreas is able to produce the right chemicals at the right times in the right quantities in order to properly digest the food we eat. After food enters the duodenum, the exocrine tissues secrete a clear, watery, alkaline juice that contains several enzymes that break down food into small molecules that can be absorbed by the intestines. These enzymes include:

Trypsin and chymotrypsin to digest proteins Amylase to break down carbohydrates Lipase, to break down fats into fatty acids and cholesterol. The endocrine portion of the pancreas, or islets of Langerhans, is composed of several cells that secrete hormones directly into the bloodstream. Insulin is a hormone secreted by pancreatic beta cells in response to a rise in blood sugar. The hormone also moves glucose from the blood into muscles and other tissues so they can use it for energy. In addition, insulin helps the liver absorb glucose, storing it as glycogen in case the body needs energy during stress or exercise.

Glucagon is a hormone secreted by pancreatic alpha cells when there is a decrease in blood sugar. Its primary job is to cause glycogen to be broken down into glucose in the liver. This glucose then enters the bloodstream in order to restore the level to normal.
