The liver is an organ in the upper
right-hand part of your abdomen. It sits under the diaphragm, and on top of the stomach,
right kidney, and intestines.
The liver is a dark reddish-brown
color, and is shaped a bit like a wedge. It weighs about 3 pounds. The liver has 2
lobes. Both are made up of 8 segments that have of 1,000 small lobes called lobules.
These lobules are connected to small tubes (ducts) that lead to larger ducts that form
the common hepatic duct. The common hepatic duct sends the bile made by the liver cells
to the gallbladder and the first part of the small intestine (duodenum) through the
common bile duct.
The liver holds about 1 pint (13%)
of your body's blood supply. There are 2 blood vessels that send blood to the liver.
Hepatic artery. This sends
oxygen-rich blood to the liver.
Hepatic portal vein. This
sends nutrient-rich blood to the liver.
