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).
The liver is the largest glandular organ in the body and performs multiple critical functions to keep the body pure of toxins and harmful substances. An average adult liver weighs about three pounds. Located in the upper-right portion of the abdominal cavity under the diaphragm and to the right of the stomach, the liver consists of four lobes. It receives about 1.5 quarts of blood every minute via the hepatic artery and portal vein.
