A milky fluid containing the fatty matter of the food in a state of emulsion, or fine mechanical division; formed from chyme by the action of the intestinal juices. It is absorbed by the lacteals, and conveyed into the blood by the thoracic duct.
Chyle is a milky fluid (bodily fluid) consisting of lymph and emulsified fats, or free fatty acids (FFAs). It is formed in the small intestine during digestion of ingested fatty foods and taken up by lymph vessels specifically known as lacteals, unlike other components of digested food that are conveyed by veins. The lacteals are much better suited for the transport of FFAs away from the gastrointestinal tract.
