Word hepatitis comes from the Ancient Greek word hepar (root word hepat) meaning ‘liver’, and Latin it’s meaning inflammation.
Hepatitis means injury to the liver with inflammation of the liver cells. What is the liver? The liver is the largest gland in the human body. It weighs approximately 3 lb (1.36 kg). It is reddish-brown in color and is divided into four lobes of different sizes and lengths. It is also the largest internal organ (the largest organ is the skin). It is below the diaphragm on the right in the thoracic region of the abdomen. Blood reaches the liver through the hepatic artery and the portal vein. The portal vein carries blood containing digested food from the small intestine, while the hepatic artery carries oxygen-rich blood from the aorta.
