liver, largest glandular organ of the body, weighing about 3 lb (1.36 kg). It is reddish brown in color and is divided into four lobes of unequal size and shape. The liver lies on the right side of the abdominal cavity beneath the diaphragm. Blood is carried to the liver via two large vessels: the hepatic artery carries oxygen-rich blood from the aorta, and the portal vein carries blood containing digested food from the small intestine. These blood vessels subdivide in the liver repeatedly, terminating in minute capillaries. Each capillary leads to a lobule. Liver tissue is composed of thousands of lobules, and each lobule is made up of hepatic cells, the basic metabolic cells of the liver. One of the liver's major functions is the manufacture and secretion of bile, which is stored in the gall bladder and released in the small intestine. Bile salts emulsify fats, a process that prepares the latter for digestion by the intestinal enzymes (see digestive system). The hepatic cells assimilate carbohydrates, fats, and proteins. They convert glucose to its stored form, glycogen, which is reconverted into glucose as the body requires it for energy. The ability of the liver to maintain the proper level of glucose in the blood is called its glucose buffer function. The end products of fat digestion, fatty acids, are used to synthesize cholesterol and other substances needed by the body. Excess carbohydrates and protein are also converted into fat by the liver. Digested proteins in the form of amino acids are broken down further in the liver by deamination. Part of the amino acid molecule is converted into glycogen and other compounds. Urea, a waste product of protein breakdown, is produced by the liver, a process which removes poisonous ammonia from the body fluids. The liver is also capable of synthesizing certain amino acids (the so-called nonessential amino acids) from other amino acids in a process called transamination. Some essential components of blood are manufactured by the liver, including about 95% of the plasma proteins and the blood-clotting substances (fibrinogen, prothrombin, and other coagulation factors). The liver also filters harmful substances from the blood. Phagocytic cells in the liver, called Kupffer cells, remove large amounts of debris and bacteria. In addition, the liver stores important vitamins and minerals, including vitamins A, D, K, and B12. Several diseases states can affect the liver, such as hepatitis (an inflammation of the liver) and cirrhosis (a chronic inflammation that progresses ultimately to organ failure). Alcohol alters the metabolism of the liver, which can have overall detrimental effects over long periods of abuse. In 1994, a bioartificial liver, part machine, part cloned living liver cells, was used for the first time. Functioning somewhat like a kidney dialysis machine, the bioartificial liver can support patients with acute liver failure until their own livers regenerate, or it can be used by patients while waiting for a liver transplant.

John "Liver-Eating" Johnson (c.1824January 21, 1900) was a mountain man of the American West.

Johnson is the basis for the fictional character Jeremiah Johnson.


Johnson is said to have been born in New Jersey with the name John Garrison. Some accounts say that he joined the United States Navy in 1846 during the Mexican-American War but, after striking an officer, he deserted, changed his name to John Johnston, and traveled west to trap and hunt in Wyoming. He also became a "woodhawk," supplying cord wood to steamboats. He was described as a large man, standing around six feet tall and weighing over two hundred pounds.

Rumors, legends and campfire tales abound about Johnson. Perhaps chief among them is this legend: In 1847, his Native American wife was killed by members of the Crow tribe, which prompted Johnson to embark on a 20-year vendetta against the tribe. The legend says that he would cut out and eat the liver of each man killed, but it's quite possible that this only happened once and that he just pretended to eat the liver. In any case, he eventually became known as "Liver-Eating Johnson" (usually spelled without the t in Johnston). Since eating the liver of a victim is a symbolic way of completing a revenge slaying, some credence might be given to this activity.

Another story is when Johnson was ambushed by a group of Blackfoot warriors in the dead of winter on a foray to visit his Flathead kin, a trip that would have been over five hundred miles. The Blackfoot planned to sell him to the Crow, his mortal enemies, for a handsome price. He was stripped to the waist, tied with leather thongs and put in a teepee with an inexperienced guard outside. Johnson managed to chew through the straps, then knocked out his young guard with a two-finger jab between the eyes, took his knife and scalped him, then quickly cut off one of his legs. He made his escape into the woods, and survived on the Blackfoot's leg until he reached the cabin of Del Gue, his trapping partner, more dead than alive, a journey of about two hundred miles.

Eventually, Johnson made peace with the Crow, who became "his brothers", and his personal vendetta against them finally ended after twenty-five years and scores of Crow warriors had fallen. The West, however, was still a very violent and territorial place, particularly during the Plains Indian Wars of the mid 1800s. Many more Indians of different tribes, especially but not limited to, the Sioux and Blackfoot, would know the wrath of "Dapiek Absaroka" Crow killer and his fellow mountain men.

The above information is based upon the yarns and tales told over and over through the years. The novel Mountain Man by Vardis Fisher is a good fiction source. The accurate story is told in the diaries of Lee and Kaiser who were on the Missouri River in 1868 when Johnston was given his moniker after a rainy fight with the Sioux.

He joined the Union Army in St. Louis in 1864 (Co. H, 2nd Colorado Cavalry) as a private, and was honorably discharged the following year. During the 1880s he was appointed deputy sheriff in Coulson, Montana, and a town marshal in Red Lodge, Montana. He was listed as five foot, eleven and three-quarter inches tall according to government records.

In December 1899, he was admitted to a veteran's hospital in Sawtelle, California, now a part of Los Angeles. He died the next month at the age of approximately seventy-six. He was first interred in nearby Sawtelle National Cemetery. On June 8, 1974, Johnson's body was removed to Cody, Wyoming. He is hence buried at Old Trail Town in Cody, along with several other local "Old West" characters.
