The liver is divided into four lobes. This image shows the large right lobe and a smaller left lobe separated by the falciform ligament. 1: Right lobe of liver. 2: Left lobe of liver. 3: Quadrate lobe of liver. 4: Round ligament of liver. 5: Falciform ligament. 6: Caudate lobe of liver. 7: Inferior vena cava.
The caudate lobe is a separate structure which receives blood flow from both the right- and left-sided vascular branches. [5] [6] The Caudate lobe includes: (1) the Spiegel lobe; (2) the paracaval portion; and (3) the caudate process portion. The Spiegel lobe has its portal venous and biliary branches ramified mainly from the left-side tract.
The liver, viewed from above, showing the left and right lobes separated by the falciform ligament. The liver is a dark reddish brown, wedge-shaped organ with two lobes of unequal size and shape. A human liver normally weighs approximately 1.5 kilograms (3.3 pounds) [11] and has a width of about 15 centimetres (6 inches). [12]
The porta hepatis or transverse fissure of the liver is a short but deep fissure, about 5 cm long, extending transversely beneath the left portion of the right lobe of the liver, nearer its posterior surface than its anterior border. It joins nearly at right angles with the left sagittal fossa, and separates the quadrate lobe in front from the ...
The round ligament of the liver, ligamentum teres or ligamentum teres hepatis is a ligament that forms part of the free edge of the falciform ligament of the liver. It connects the liver to the umbilicus. It is the remnant of the left umbilical vein. The round ligament divides the left part of the liver into medial and lateral sections.
Lobules of liver. The structure of the liver’s functional units or lobules. Blood enters the lobules through branches of the portal vein and hepatic artery proper, then flows through sinusoids. In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale.
The common hepatic duct is an important anatomic landmark during surgeries such as cholecystectomy. It forms one edge of Calot's triangle, along with the cystic duct and the cystic artery. All constituents of this triangle must be identified to avoid cutting or clipping the wrong structure.
Falciform ligament can be seen separating the left medial from the right lateral lobes of liver. In human anatomy, the falciform ligament (from Latin ' sickle -shaped') is a ligament that attaches the liver to the front body wall and divides the liver into the left lobe and right lobe. [1] The falciform ligament is a broad and thin fold of ...
