The pancreas delivers its enzymes to the small intestine in an alkaline-rich fluid.

Explanation:

The pancreas deliver the necessary enzymes required for digestion in a fluid. This fluid has an alkaline pH so that the enzymes are able to get their optimal alkaline pH at which they can function. Beyond these pH, the enzymes will become denatures and will not be able to carry out the process of digestion.

The pancreatic juice contains the alkaline bicarbonate in it. This bicarbonate neutralizes the acidic condition in the small intestine.
