secretin

/ sɪˈkriːtɪn /

First recorded in 1900–05; secrete ¹ + -in ²

C20: from secretion + -in

This acid, on striking the lining of the small intestine, causes the formation in its walls of a substance known as secretin.

This secretin reaches the blood and seems to stimulate all the glands pouring fluid into the intestine to do more work.

In such cases the pancreas and liver must be stimulated to secretion by some other mechanism than secretin.

The claims for Secretogen are based on the physiologic action of secretin as described by various observers.

Some observers have claimed that secretin is absent in cases of diabetes in which the pancreas is still found normal.
