These structures run longitudinally along the edges of the lobule, which has an elongated or more massive and sometimes club-shaped appearance (Pfuhl 1932; Bargmann 1977). In the rat, however, adjacent liver lobules merge and there is no regular distribution of the portal areas in the lobular ...
The liver has four lobes: left, right, caudate, and quadrate. These lobes are further divided into lobules, which are composed of millions of hepatic...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
At the smallest scale, the shape of the liver elemental systems—the lobules—is discovered, while their permeability is also predicted. The theory is compared with good agreement to anatomical data from the literature.doi:10.1038/s41598-020-73208-8Aczel Sanchez...
An adult female breast consists of around 20 lobes of glandular tissue where each lobe is made up of several lobules that radiate around the nipple. Each of these lobules is composed of a group of alveoli that terminate into small ducts, which collectively form large excretory ducts called lac...

The liver lobule is an elongated unit of hepatic cells with a polygonal cross-section containing a three-dimensional lattice of interconnected sinusoids. Lobules are not discrete vascular units as sinusoidal connections join them together. The parenchyma consists of anastomosing sheets of hepatic cells...

Histologically, the liver is wrapped with a thin capsule of fibro-connective tissue. The hepatic parenchyma is made of hepatocytes with blood sinusoids. The hepatocytes are polygonal-shaped cells and have no hepatic lobules or portal triads. Melano-macrophage centers are di...
The three-dimensional structure of endothelial cells in the hepatic sinusoids of the rat was studied by application of light- and electron microscopy on Golgi-impregnated specimens. A number of endothelial cells could thus be individually delineated throughout the hepatic lobules. The cytoplasm, ...
