Functions, location, definition, anatomy of the Human Liver

The liver is a vital organ present. The human liver has many functions. The liver removes excess amino acids from the blood, converting them to urea, which is excreted by the kidneys. The liver also synthesizes vitamins, produces bile and blood-clotting factors, and removes damaged red cells and toxins such as alcohol from the blood.

The right liver lobe is the larger of the two lobes by six times. The left liver lobe is the smaller and flatter of the two liver lobes.

The human body: Human liver

An adult human liver normally weighs between 1.4-1.6 kg (3.1-3.5 lb), and is a soft, pinkish-brown, triangular organ.

It is located in the right upper quadrant of the abdominal cavity, resting just below the diaphragm. The liver lies to the right of the stomach and overlies the gallbladder.

Many diseases of the liver are accompanied by jaundice caused by increased levels of bilirubin in the system. The bilirubin results from the breakup of the haemoglobin of dead red blood cells; normally, the liver removes bilirubin from the blood and excretes it through bile.

Some of the diseases are Wilson’s Disease, hepatitis (an inflammation of the liver), liver cancer, and cirrhosis.
