Proctitis is an inflammation of the anus and the lining of the rectum, affecting only the last 6 inches of the rectum.
The liver lies on the right side of the abdominal cavity beneath the diaphragm. Blood is carried to the liver via two large vessels called the hepatic artery and the portal vein. The heptic artery carries oxygen-rich blood from the aorta (a major vessel in the heart).
Primary functions of the liver. The liver is the largest organ in the body. It is located below the diaphragm in the right upper quadrant of the abdominal cavity. An adult's liver weighs approximately 3 pounds and extends approximately from the right 5th rib to the lower border of the rib cage. The liver is separated into a right and left lobe, separated by the falciform ligament. The right lobe is much larger than the left lobe. The working cells of the liver are known as hepatocytes.
