lacteals

the central lymph vessels in the villi of the vertebrate intestine into which neutral fat is passed from the columnar epithelium where it has been resynthesized from fatty acids and glycerol. The fat is in the form of a white emulsion of minute globules, giving lymph a milky appearance (hence the name ‘lacteal’) and is carried to all parts of the body.
