Function of Kupffer cells
Liver contains macrophages called Kupffer cells. These cells engulf and breakdown toxic matter such as microorganisms, dead cells and chemicals. Kupffer cells ingest microorganism by phagocytosis. The engulfed microorganism is called phagosome. Lysosmes in the cytoplasm of kupffer cell, fuse with the phagosome and release digestive enzymes. These enzymes breakdown and kill the microorganism.
But how does kupffer cell identify toxic matter?
There are receptors for the toxic matter on the surface of kupffer cells. The harmful particle and these receptors of kupffer cell can fit together like pieces of a puzzle. The harmful particle is then engulfed by kupffer cell.

Kupffer cells are phagocytes located in the?
Kupffer cells are phagocytes which line the sinusoids of the liver.
Where would you find the kupffer cells of the liver?
They line the sinusoids.
What liver function test indicates excessive breakdown of red blood cells?
Indirect bilirubin
Dna makes what protein in a cell?
DNA does not manufacture specific proteins. It codes for many different proteins that depend upon the cell's function. Liver cells' DNA manufactures different proteins that match the function of the liver. Kidney cells' DNA manufactures different proteins that match the function of the kidneys.
How does the liver do its job?
Functions of Liver1: Regulation of blood glucose levelWhen the blood glucose concentration becomes excessive; liver converts the glucose into glycogen. Liver converts the glycogen back to the glucose when energy is needed.2: MetabolismLiver is responsible for the metabolism of proteins and fats. It synthesizes blood clotting factors and stores various types of vitamins.3:Bile secretionThe hypatocystes (cells) of liver secrete bile. The bile is stored in gallbladder.The bile duct of liver and cystic duct of gallbladder form common bile duct. The common bile duct join the pancreatic duct, the bile from common bile duct and pancreatic juice from pancreatic duct empty into duodenum (of small intestine) through the sphincter of oddi (valve) if it is opened. The opening of this valve is controlled by a hormone called Cholecystokinin.Bile juice helps in emulsificaton of fats.Bile is alkaline solution. Its molecules have dual nature (one end is attracted to water molecule while other is attracted to fat molecule). Thus its molecules remain in between water molecules and fat molecules (emulsification process).If bile molecules were not present between fats and water, the fat molecules would be repelled by water molecules and be attracted to each other. The fat molecules would merge together because fats are insoluble in water. The merged fats would not be easily broken down with lipase (fat digesting enzyme).4:Breakdown of old red blood cellsLiver breaks down the old red blood cells into bilurubin. Bilurubin is excreted in bile and urine.5: DetoxificationLiver contains macrophages called Kupffer cells. These cells engulf and breakdown toxic matter such as microorganisms, dead cells and chemicals. Kupffer cells ingest microorganism by phagocytosis. The engulfed microorganism is called phagosome. Lysosmes in the cytoplasm of kupffer cell, fuse with the phagosome and release digestive enzymes.

Kupffer cells are phagocytes located in the?
Kupffer cells are phagocytes which line the sinusoids of the liver.
What type of cell is the Kupffer cell?
Kupffer cells are specialised macrophages that are found in the sinusoids of the liver.
Where are poisons broken down in the digestive system?
The liver is the organ in the body that cleans poisons out of the system. Red blood cells and Kupffer cells are formed in the liver. Red blood cells carry oxygen and Kupffer cells eliminate microorganisms.
Where would you find the kupffer cells of the liver?
They line the sinusoids.
What is the function of macrophage?
They form part of sinusoid wall of the liver, and remove debris such as bacteria and worn out blood cells from the blood as it flows past. Also kown as Kupffer Cells
Where would you expect to find the hepatic macrophages of the liver?
Hepatic macrophages are special phagocytic cells, also called Kupffer cells, that line the sinusoids and remove debris from the blood.
Where are the kupffers cells located?
Kupffer cells are tissue-associated macrophages or histiocytes that are found primarily in the sinusoids of the liver.

What is the tissues of the liver and their function?
Liver tissue is made up of two types of cells: karat parenchymal and non-parenchymal cells. The karat parenchymal cells are known as hepatocytes. There are several types of non-parenchymal cells: Sinusoidal hepatic endothelial cells, Kupffer cells and hepatic stellate cells. The liver has a number of functions, including synthesizing hormones and breaking down substances for metabolization by the body's various systems.
What it the function of the kupffer cells in the liver?
Kuppfer cells are macrophages, with an important role in our defense system. They are found in the liver, more precisely, in the sinusoids, lining the walls of these channel-like vessels, between the hepatic plates, - a very good place to filter through the blood, clearing it from bacteria, foreign materials, old/damaged cells, and even antigens.
What do kupfer cells secrete?
Kupffer cells, also known as Browicz-Kupffer cells, are specialized macrophages located in the liver that form part of the reticuloendothelial system (aka: mononuclear phagocyte system). The cells were first observed by Karl Wilhelm von Kupffer in 1876.[1] The scientist called them "sternzellen" (star cells or stellate cells) but thought, falsely, that they were an integral part of the endothelium of the liver blood vessels and that they originated from it. In 1898, after several years of research, Tadeusz Browicz, a Polish scientist, identified them, correctly, as macrophages. [2][3] Their development begins in the bone marrow with the genesis of promonocytes and monoblasts into monocytes, and then on to peripheral blood monocytes, completing their differentiation into Kupffer cells.[4] The red blood cell is broken down by phagocytic action, and the hemoglobin molecule is split. The globin chains are reutilized, while the iron-containing portion or heme is further broken down into iron, which is reutilized and bilirubin, which is conjugated with glucuronic acid within hepatocytes and secreted into the bile. Helmy et al. identified a receptor present in Kupffer cells, the complement receptor of the immunoglobulin family (CRIg). Mice without CRIg could not clear complement system-coated pathogens. CRIg is conserved in mice and humans and is a critical component of the innate immune system.[5] Kupffer cells activation are responsible for early ethanol-induced liver injury, common in chronic alcoholics. Chronic alcoholism and liver injury deal with a two hit system. The second hit is characterized by an activation of the Toll-like receptor 4 (TLR) and CD14, receptors on the Kupffer cell that internalize endotoxin (LPS). This activates the transcription of pro-inflammatory cytokines (TNF alpha) and production of superoxides (a pro-oxidant). TNFalpha will then enter the stellate cell in the liver, leading to collagen synthesis and fibrosis. Fibrosis will eventually cause cirrhosis, or loss of function of the liver
