Description of the Liver—Secretion of Bile; its Uses, etc.—Gall-bladder- Inflammation of the Liver—Hydatids—Jaundice, or Yellows. Description of the Liver. THE liver is the largest gland in the body. Unlike the liver of a horse, it has a large reservoir for the reception of the bile, called the gall-bladder. In form it is irregular, being convex anteriorly, or toward the diaphragm, with which it is in contact, and concave on its posterior surface, or toward and in the vicinity of a part of the stomach. It is composed of two lobes. That on the right side is the larger. The central portion of the gland is the thickest, and it gradually becomes thin toward its borders. The mass consists of a vast number of minute lobules, varying in size and form, containing a net-work of biliary ducts connected with their main trunks, and a large number of biliary cells; and each is connected, in like manner, with three blood-vessels; namely, the hepatic or nutrient artery of the liver; the vena porta, which returns the venous blood after it has circulated through the intes- tines ; the hepatic vein, which carries back the blood received from both the other sources. It will be seen, therefore, that the venous blood, which is brought to the liver by the vena portse, is intended for the elimination of bile; therefore this vessel seems to act in the double capacity of vein and artery; for, as a vein, it receives blood from the abdominal viscera; as an artery it ramifies through the liver, forms a capillary net-work, and then secretes the bile. From this capillary net-work, which can be traced to the center of the minute lobules, the hepatic vein takes its origin, collecting the blood from the capillary net-work. It then unites with other (611). Please note that these images are extracted from scanned page images that may have been digitally enhanced for
