With illustrations and an appendix of useful tables. Feeds; Cattle; Nutrition. 68 MANUAL OF CATTLE-FEEDIIS-G. Fig. o shows a longitudinal section of a villns, in wliieli a represents tlio epitlielial cells, h the capillary blood-\ es- sels, 0 the lajer of muscular libres, and d the lacteal. Lacteals and ™The lacteals unite into larger ones leading to the mesenterio ffkmds, and after leaving these, finally join the thoracic duei, a large vessel leading forward (in man upward) and emptying into a vein in the left side near the collar-hone, called the left sulclavlan vem, near its entrance into the heart. They derive their name from a milky- looking fluid wath which they are filled during digestion, and which ow^es its ap- pearance to the digested and emulbificd fat of the food which has been resorbed from the chyle. At other times they contain a clear or opalescent li(piid called lympli. The capillaries of the intestines also unite into larger vessels, and finally into one, the jpoHal vein, leading to the liver. (Compare fig. 4, p. 77.) There the blood which it carries is distributed through a second set of capillaries in that organ, and then reunited again into a single vein, the IhejyatiG veitij leading almost directly to the heart. Phenomena of Resorption.—As soon as the food passes from the stomach into the intestines, the resorbents of the latter begin their work, and the two processes of digestion and resorption go on simultaneously. Ouj' knowledge of the processes of resorption is not as full as might be wished. We know that liquids and soluble substances brought into the intestines, rapidly disappear. Fig. 3,—(Irey). ;.
