Alimentary absorption is effected mostly pjg, 135. in the small intestines. The lacteals com-mence by villi in the mucous surface, eachtube beginning in a single villus by a closedextremity; the trunk arising from each villusis formed by the confluence of a number ofsmaller branches, which anastomose freelywith eacli other in the form of loops, as infig. 135, never commencing in open extremi-ties. These loops are embedded in a mass ofcells at the extremity of each villus; these lacteal origincells exercise the selec ing or transmutingpower o«ev the nutritive dements when full their contents are yielded. 172 PHYsiOLoair. to the absorbenr vessels, either bj a process of deliquescence 01 oursting, their pmce being sup^-ied by fresh cells, and so the process is contuiued till the nutritive material is exhausted; after which the villi,previously turgid, becomes flaccid, and the epithelium, which was removed during the process of absorption, is renewed; the lacteal vesselsthen become the interstitial absorbent vessels of the intestinal canaland act the part of lymphatics.
