Where is the Liver?

where is the liver

The liver is the largest solid organ in the body, located in the upper right quadrant of the abdomen. It weighs approximately three pounds and is about the size of a football. Its functions include metabolizing proteins, carbohydrates, and fats. It also stores vitamins and glycogen. In addition, the liver synthesizes blood clotting factors and removes wastes from the blood. A malfunctioning liver can lead to numerous symptoms, including nausea, vomiting, and tar-colored stool.

The liver receives blood from two main sources, the portal vein and the hepatic artery. The portal vein carries oxygen-rich blood, while the hepatic artery carries nutrients from the intestines to the rest of the body. The portal vein and the hepatic artery are connected by capillary-like tubes called sinusoids. Each sinusoid is lined with Kupffer cells, which break down red blood cells as they pass through them.

The liver consists of two main lobes, separated by a ligament called the falciform. The liver is covered by a protective fibro-elastic capsule known as the Glaisson’s capsule. This sheath keeps the liver in place and protects it from damage. It is the second most massive organ in the body. It also has the largest volume of blood. Its surface area is approximately one-third of the size of the liver.

In addition to metabolizing fatty acids and producing energy, the liver plays an important role in lipid metabolism. It produces cholesterol and triglycerides and a majority of the body’s lipoproteins. It also has an important role in digestion, emulsifying fats for absorption of vitamin K. It also manufactures insulin-like growth factor 1, which plays an important role in childhood growth and continues to have anabolic effects in adults.
