secretin
(seh-KREE-tin)
A hormone released into the blood by cells in the inner layer of the small intestine. It is released when partly digested food moves from the stomach into the small intestine. Secretin causes the pancreas, liver, and stomach to release other substances that help digest food. Secretin may also be made in the laboratory.
