The liver consists of two large parts: The right lobe with a length (0.13±35.13) mm, and the left lobe with a length (0.3 3±28.50) mm and is characterized with a reddish-brown colour.

Further, it appears in oval or pear shape and has green colour; it consists of the head, body and neck. The liver parenchyma consists of hepatocyte cells arranged in the form of cords known as hepatic cords arranged radially towards the central vein, spread within the parenchyma of the liver portal area, surrounded by connective tissue. Besides, it includes the hepatic portal area, branch hepatic artery, bile duct lymphatic vessels, which are scattered within the connective tissue surrounding the portal area. The gallbladder consists of the mucous tunic consisting of elongated columnar cells with basal oval nuclei located, below them is the lamina propria, then a layer of smooth muscle fibers arranged to form the tunica muscularis, followed by the tunica serousa or adventitia, which consists of loose connective tissue.
