The caudate lobe (posterior hepatic segment I, Spigelian lobe) is situated upon the postero-inferior surface of the liver on the left lobe of the liver, opposite the tenth and eleventh thoracic vertebrae. The right lobe is much larger than the left the proportion between them being as six to one The left lobe is smaller and more flattened than the right It is situated in the Epigastric and left Hypochondriac regions The quadrate lobe is an area of the Liver situated on the under surface of the right lobe bounded in front by the Anterior margin of the liver; behind by the For other structures with similar name see Round ligament. In Anatomy, the round ligament of (the liver (also commonly known by its The falciform ligament is a broad and thin antero-posterior peritoneal fold falciform (Latin "sickle-shaped" in shape its base being directed downward and backward its apex The inferior vena cava (or IVC is the large Vein that carries de-oxygenated Blood from the lower half of the body into the Heart. Bile, which is synthesized in the liver is carried to the right and left hepatic ducts which converge along with the Cystic duct to form the Common hepatic duct. The cystic duct is the short Duct that joins the Gall bladder to the Common bile duct. The common hepatic duct is the duct formed by the convergence of the Right hepatic duct (which drains bile from the Right functional lobe of the liver) and the The gallbladder (or cholecyst sometimes gall bladder is a small organ whose function in the body is to store Bile and aid in the digestive process Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Gray's Anatomy the Respiratory apparatus ( Apparatus Respiratorius Respiratory system Respiratory apparatus The 12 thoracic vertebrae compose the middle segment of the Vertebral column, between the Cervical vertebrae and the Lumbar vertebrae. It is bounded on the left side by the physiological division of the liver called the ligamentum venosum. The ligamentum venosum is the fibrous remnant of the Ductus venosus of the Fetal circulation.
It is bounded, below, by the porta; on the right, by the fossa for the inferior vena cava; and, on the left, by the fossa for the ductus venosus. The inferior vena cava (or IVC is the large Vein that carries de-oxygenated Blood from the lower half of the body into the Heart. In the Fetus, the ductus venosus shunts a significant majority (80% of the blood flow of the Umbilical vein directly to the Inferior vena cava.
It looks backward, being nearly vertical in position; it is longer from above downward than from side to side, and is somewhat concave in the transverse direction.
The caudate process is a small elevation of the hepatic substance extending obliquely and laterally, from the lower extremity of the caudate lobe to the under surface of the right lobe. The right lobe is much larger than the left the proportion between them being as six to one
It is situated behind the porta, and separates the fossa for the gall-bladder from the commencement of the fossa for the inferior vena cava. The gallbladder (or cholecyst sometimes gall bladder is a small organ whose function in the body is to store Bile and aid in the digestive process The inferior vena cava (or IVC is the large Vein that carries de-oxygenated Blood from the lower half of the body into the Heart.
