. The comparative anatomy of the domesticated animals. Horses; Veterinary anatomy. Fig. 279. PERPENDICULAR SECTION THROUGH THI'^ INTESTINAL WALL TO SHOW A SOLITARY FOLLICLE. a, Lieberkiihnian glariils; 6, solitary follicle; c, lacteal vessels stirmunding, but not ]ienetrating, the follicles; d, large efferent vessels, provided with valves. 4. Vessels and nerves.—The small intestine receives its arteries almost ex- clusively from the great mesenteric artery. One, which goes to the duodenum, comes from the cceKac trunk. These arteries form a submucous network, from which branches pass inwards and outwards, the first to the muscular and serous tunics, the second to the glands and the villi. A tubular network surrounds each Lieberkiihnian gland, and is observed in each villus; while a spherical reticulation surrounds each solitary follicle, loops being given off which penetrate nearly to the centre of the follicle. The veins have the same arrangement, and finally enter the vena portse. The lymphatics constitute three superposed networks in the mucous membrane. The first is situated around the glandular orifices ; it receives the central lacteal from each villus ; the second is placed between the glandular and the muscular layer of the mucous membrane ; the third lies in the deep portion of the membrane, and communicates with the meshes encircling the solitary glands. The largest emergent vessels from these three networks pass through the wall of the intestine, accom- panying the blood-vessels between the layers of the mesentery, enter the mesenteric glands, and terminate in the reservoir of Pecquet {receptaculum chyli). There is another lymphatic network in the muscular tunic of the VILLI OF INTESTINE, WITH THEIR CAPILLARY PLEXUS Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
