What secretes salts, acids, and enzymes, which continue the breakdown of proteins, fats and carbohydrates

The pancreas secretes trypsin and chymotrypsin enzymes which continue breakdown proteins into smaller peptides and some single amino acids. Carboxypeptidase also secreted by the pancreas splits single amino acids from the carboxyl end of proteins. Bile, which contains a mix salts, is secreted by the liver .
