The upper small intestine secretes the hormones Cholecystokinase and secretin, mucous, Intestinal digestive juices, and possibly enzymes. The Digestive enzymes are The small intestine secretes about 1800 ccs a day. The pH of the small intestine secretions averages 7.5 to 8.0.
Enzymes such as amylases and proteases break down large molecules (starch or proteins, respectively) into smaller ones, so they can be absorbed by the intestines. Starch molecules, for example, are too large to be absorbed from the intestine, but enzymes hydrolyze the starch chains into smaller molecules such as maltose and eventually glucose, which can then be absorbed.
