In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue , consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein .
A liver segment is one of eight segments of the liver as described in the widely used Couinaud classification (named after Claude Couinaud) in the anatomy of the liver.This system divides the lobes of the liver into eight segments based on a transverse plane through the bifurcation of the main portal vein, [1] arranged in a clockwise manner starting from the caudate lobe.
The liver is responsible for the mainstay of protein metabolism, synthesis as well as degradation. All plasma proteins except Gamma-globulins are synthesised in the liver. [50] It is also responsible for a large part of amino acid synthesis. The liver plays a role in the production of clotting factors, as well as red blood cell production.
Researchers hope the technology will enable greater surgery accuracy and improve outcomes for patients with liver cancer. 3D printed liver model created to help surgeons prepare for difficult ...
The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). [2] The liver is the biggest gland of the body. It has a wide variety of functions that range from the destruction of old blood cells to the control of the whole metabolism of macromolecules . [ 3 ]
A liver sinusoid is a type of capillary known as a sinusoidal capillary, discontinuous capillary or sinusoid, that is similar to a fenestrated capillary, having discontinuous endothelium that serves as a location for mixing of the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.
Figure drawing by Leonardo da Vinci. A figure drawing is a drawing of the human form in any of its various shapes and postures, using any of the drawing media. The term can also refer to the act of producing such a drawing. The degree of representation may range from highly detailed, anatomically correct renderings to loose and expressive sketches.
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.
