Chyle (from the Greek word chylos, meaning juice) is a milky bodily fluid consisting of lymph and emulsified fats, or free fatty acids (FFAs). It is formed in the small intestine during digestion of fatty foods, and taken up by lymph vessels specifically known as lacteals. The relative low pressure of the lacteals allows large fatty acid molecules to diffuse into them, whereas the higher pressure in veins allows only smaller products of digestion, like amino acids and sugars, to diffuse into the blood directly.
