succus entericus

http://www.fofweb.com/subscription/science/Helicon.asp?SID=2&iPin=ffdbichem1907

The viscous alkaline secretion produced by Brunner's glands in the wall of the duodenum. It consists of water, hydrogencarbonate ions, and mucoproteins, and serves to protect the walls of the small intestine from the corrosive effects of the acidic and proteolytic chyme entering from the stomach. It was formerly thought to contain digestive enzymes, but all duodenal enzymes are now known to be localized on or within the epithelial cells.

chyme
http://www.encyclopedia.com/html/c1/chyme.asp
semiliquid substance found in the stomach and resulting from the partial digestion of food by the salivary enzyme amylase, the gastric enzyme pepsin, and hydrochloric acid.

I think it boils down to:
chyme - broken down food and digestive enzymes beginning with stomach
succus entericus - no food, no digestive enyzmes made in duodenum
