Fig. 81.—Diagrammatic section through villi of small intestine. (From Bohm and Davidoff, after Mall.) Fats are probably absorbed as glycerine and soaps, although possibly also in the form of emulsified fats, and pass through these outer cells of the villi into the lymph vessels or lacteals. During the process of this absorption the glycerine unites with the fatty acids of the soaps to form fats, so that the lymph as it leaves the villi is charged with liquid globules of fat to such an extent as to give it the appearance of milk. The lymph vessels join the thoracic duct from which the fatty particles are discharged into the veins and thus get into the general circulatory system of the blood. The proteins in the form of pei)tones or possibly amino- acids are absorbed into the blood-vessels of the \illi, during which process they combine to form the serum-albumin.
