The hepatocyte plates are one cell thick in mammals and two cells thick in the chicken. Sinusoids display a discontinuous, fenestrated endothelial cell lining. The endothelial cells have no basement membrane and are separated from the hepatocytes by the space of Disse, which drains lymph into the portal tract lymphatics. [citation needed]
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.
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]
Bacterial cell division happens through binary fission or through budding. The divisome is a protein complex in bacteria that is responsible for cell division, constriction of inner and outer membranes during division, and remodeling of the peptidoglycan cell wall at the division site.
The caudate lobe of the liver is bounded below by the porta hepatis, on the right by the fossa for the inferior vena cava, and on the left by the fossa for the ductus venosus and the physiological division of the liver, called the ligamentum venosum. It looks backward, being nearly vertical in position; it is longer from above downward than ...
(Lipopolysaccharide (LPS) is a bacterial endotoxin which is found in the cell wall gram-negative bacteria, whereas lipoteichoic acid is present in gram-positive bacteria.) Because of this detection system, Kupffer cells play a critical role in initiating and mediating immune responses to bacterial infection of the liver. [4]
The perisinusoidal space also contains hepatic stellate cells (also known as Ito cells or lipocytes), which store vitamin A in characteristic lipid droplets. [ 2 ] This space may be obliterated in liver disease , leading to decreased uptake by hepatocytes of nutrients and wastes such as bilirubin .
Hepatocytes are polyhedral in shape, therefore having no set shape or design, although they are made of cuboidal epithelial cells. They have surfaces facing the sinusoids (called sinusoidal faces) and surfaces which contact other hepatocytes (called lateral faces). Bile canaliculi are formed by grooves on some of the lateral faces of these ...
