The cells are often attached to each other and also to their nearby epithelial cells mainly by gap junctions and hemidesmosomes. There is much variation in the types of cell in the parenchyma according to the species and anatomical regions. Its possible functions may include skeletal support, nutrient storage, movement, and many others. [15]
Chlorenchyma cells carry out photosynthesis and manufacture food. The shape of parenchyma cells varies with their function. In the spongy mesophyll of a leaf, parenchyma cells range from near-spherical and loosely arranged with large intercellular spaces, [2] to branched or stellate, mutually interconnected with their neighbours at the ends of ...
The various functions of the liver are carried out by the liver cells or hepatocytes. The liver is thought to be responsible for up to 500 separate functions, usually in combination with other systems and organs. Currently, no artificial organ or device is capable of reproducing all the functions of the liver. Some functions can be carried out ...
A hepatocyte is a cell of the main parenchymal tissue of the liver. Hepatocytes make up 80% of the liver's mass. These cells are involved in: Protein synthesis; Protein storage; Transformation of carbohydrates; Synthesis of cholesterol, bile salts and phospholipids; Detoxification, modification, and excretion of exogenous and endogenous substances
The name is derived from the fact that the cells undergoing this form of cell death increase in size . It is generally considered a form of apoptosis , [ 1 ] and is a descriptor used in the context of inflamed fatty liver ( steatohepatitis ) [ 2 ] (which may be due to obesity or alcohol ), as well as viral hepatitis.
This tissue provides support to plants and also stores food. Chlorenchyma is a special type of parenchyma that contains chlorophyll and performs photosynthesis. In aquatic plants, aerenchyma tissues, or large air cavities, give support to float on water by making them buoyant. Parenchyma cells called idioblasts have metabolic waste.
Liver cytology specializes in the study of liver cells. 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 liver of mammals, fowl, and fish is commonly eaten as food by humans (see offal). Pork , lamb , veal , beef , chicken, goose , and cod livers are widely available from butchers and supermarkets while stingray and burbot livers are common in some European countries.
