It divides and subdivides into smaller and smaller branches, until, in the form of the tiniest vessels, called capillaries, it passes inward among the cells to the very center of the hepatic lobules.

This is known as the hepatic duct.

The work is done by the arterial blood brought to it by a great branch direct from the aorta, known as the hepatic artery, minute branches of which in the form of capillaries, spread themselves around the hepatic lobules.

The blood, having done its work and now laden with impurities, is picked up by minute veinlets, which unite again and again till they at last form one great trunk called the hepatic vein.

After the blood has been robbed of its bile-making materials, it is collected by the veinlets that surround the lobules, and finds its way with other venous blood into the hepatic vein.

In brief, blood is brought to the liver and distributed through its substance by two distinct channels,the portal vein and the hepatic artery, but it leaves the liver by one distinct channel,the hepatic vein.

The hepatic cells appear to manufacture this glycogen and to store it up from the food brought by the portal blood.

Then, as it is wanted, the liver disposes of this stored-up material, by pouring it, in a state of solution, into the hepatic vein.

A, mesentery; B, lacteals and mesentery glands; C, veins of intestines; R.C, receptacle of the chyle (receptaculum chyli); P V, portal vein; H V, hepatic veins; S.V.C, superior vena cava; R.A, right auricle of the heart; I.V.C, inferior vena cava.

It is to be noted that the circulation of the liver is peculiar; that the capillaries of the hepatic artery unite in the lobule with those of the portal vein, and thus the blood from both sources is combined; and that the portal vein brings to the liver the blood from the stomach, the intestines, and the spleen.

The fine bands, or septa, which serve as partitions between the hepatic lobules, and so maintain the form and consistency of the organ, are the special subjects of the inflammation.

A certain part of the systemic or greater circulation is often called the portal circulation, which consists of the flow of the blood from the abdominal viscera through the portal vein and liver to the hepatic vein.

The blood, thus laden with certain products of digestion, is carried to the liver by the portal vein, mingling with that supplied to the capillaries of the same organ by the hepatic artery.

From these capillaries the blood is carried by small veins which unite into a large trunk, the hepatic vein, which opens into the inferior vena cava.

Hepatic (Gr. he#x1F27;par, the liver).

Suddenly, as he was beginning to grow discouraged, he had an inspiration one day, when he was giving a lady suffering from hepatic colics an injection of morphine with the little syringe of Pravaz.

The first proceeds from the sole fault of the brain, and is called head melancholy; the second sympathetically proceeds from the whole body, when the whole temperature is melancholy: the third ariseth from the bowels, liver, spleen, or membrane, called mesenterium, named hypochondriacal or windy melancholy, which [1086]Laurentius subdivides into three parts, from those three members, hepatic, splenetic, mesaraic.

The saturnine, hepatic, and natural lines, making a gross triangle in the hand, argue as much;" which Goclenius, cap.

12, reduceth to three, mesentery, liver, and spleen, from whence he denominates hepatic, splenetic, and mesaraic melancholy.

Hepatic action, doctors say, is very hard to start, And if you have too much of it, that also makes you smart;
