Vertical section of the intestinal mucous membrane of the rabbit. Two villi are represented, in one of which the dilated lacteal alone is shown, in the other the blood vessels and lacteal are both seen injected, the lacteal white, the blood vessels dark; a, the lacteal vessels of the villi; a', horizontal lacteal, which they join; b, capillary blood vessels in one of the villi; c, small artery; d, vein; e, the epithelium covering the villi; g, tubular glands or crypts of Lieberkuhn, some divided down the middle, others cut more irregularly; i, the submucous layer. A, cross-section of three tubular glands more highly magnified.

"In the figure on the left are seen the artery and vein of a villus. In the right figure are represented the central lacteal of the villus, with the plexus of lymph vessels at the base. The mucous, submucuous, muscular, and serous coats are indicated at the base of the right-hand figure. The epithelium of each villus is well shown." &mdash; Blaisedell, 1904

"The lacteals conduct the chyle from the intestines into numerous glands nearby, called the mesenteries, from which a fewer number of lacteals lead the chyle into one large tube in front of the spinal column, called the thoracic duct." &mdash;Brown, 1884
