The Liver is the body's largest gland, weighing about three to four pounds. It is located beneath the diaphragm in the right upper quadrant (RUQ) of the abdominal cavity. Without the liver, our bodies would be poisoned and unfit for us to do anything at all. It is a metabolically active organ responsible for many vital life functions. The primary functions of the liver are: Bile productions and excretion. Excretion of bilirubin, cholesterol, hormones, and drugs. Metabolism of fats, proteins, and carbohydrates. Enzyme activation. Storage of glycogen, vitamins, and minerals. Synthesis of plasma proteins, such as albumin, and clotting factors. And blood detoxification and purification.
The liver is the body's energy factory.

The bile moves into the gallbladder via tiny tubes. The bile is stored in the gallbladder and waits, becoming concentrated, for the signal to be released into the duodenum aiding in digestion. Without bile, the body could not digest fats, as fats do not absorb into water. The bile acts as a detergent and allows the two to mix.
The liver is an unusual organ because nearly every one of its cells is exactly alike. The working cells of the liver are known as hepatocytes. Hepatocytes have a unique capacity to reproduce in response to liver injury. Liver regeneration can occur after surgical removal of a portion of the liver (hepatectomy) or after injuries that destroy parts of the liver. And this regeneration can adjust its size to match its host. Within a week after partial hepatectomy, hepatic mass is back essentially to what it was prior to surgery. Even though the liver has the ability to react to damage and can repair itself, repetitive insults can produce liver failure or deadly diseases, infections, and disorders. A few such diseases are viral hepatitis, yellow fever, and rubella. Some of the disease caused by bacteria are amebic dysentery, leptospirosis, and streptococcal infections. These diseases can fatally damage the liver.
Liver failure is the acute failure of the liver to perform its body function. Proteins that allow the blood to clot are not produced so the patient bruises and bleeds easily. A viscous fluid will sometimes collect
