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

The pancreas secretes and chyotrypism enzymes which continue breakdown into smaller peptides and some single amnio 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. bile salts help to continue digestions of fats by attaching to small far droplets thereby increasing their surface area so that they can be further broken down by lipase enzymes
