8 sie 2023 · In histological terms, the liver consists of a large number of microscopic functional units that work in unison to ensure the overall, proper activity of the entire organ. There are three possible ways of describing one such unit, as given below: Hepatic (classic) lobule; Portal lobule; Liver acinus; Hepatic (classic) lobule

In general, the reproduction and transmission of fungi can be carried out via asexual (or mitospores) and/or sexual spores (or meiotic spores), which can be haploid, diploid or polyploid, with each one having their own characteristics in terms of morphology, size and ornamentation color.
Although liver morphology has been studied for more than 350 years, 1 in this essay we explore historical contributions by Frances Glisson, Ewald Hering, Franklin Mall, and Aron M. Rappaport, the champions of liver microanatomy, as well as recent refinements of their discoveries.
10 wrz 2024 · The liver performs a wide range of vital functions, which can be categorised into filtration, metabolic, storage, synthetic, and detoxification functions. Filtration. The liver receives and filters venous blood from the intestines, and any contaminants are removed by special phagocytes called Kupffer cells, which line hepatic sinusoids. Metabolic
30 paź 2023 · The liver is a large organ found in the upper right quadrant of the abdomen. It is a multifunctional accessory organ of the gastrointestinal tract and performs several essential functions such as detoxification, protein synthesis, bile production and nutrient storage to name only a few.
Liver functional unit classification schemes • Lobule first described by Weppler, 1665 • Functional anatomy still not fully known! • Three main models: – Classical lobule – Rappaport’s acinus model – Matsumoto’s primary lobule
Discoveries regarding the functional heterogeneity of the various liver cell types, including hepatocytes, hepatic stellate cells, sinusoidal endothelia, and Kupffer cells, are providing new insights into our understanding of the development, prevention and treatment of liver disease.
