<P> Brush border cells are found in the following main locations: </P> <Ul> <Li> The small intestine tract: This is where absorption takes place . The brush borders of the intestinal lining are the site of terminal carbohydrate digestions . The microvilli that constitute the brush border have enzymes for this final part of digestion anchored into their apical plasma membrane as integral membrane proteins . These enzymes are found near to the transporters that will then allow absorption of the digested nutrients . </Li> <Li> The kidney: Here the brush border is useful in distinguishing the proximal tubule (which possesses the brush border) from the distal tubule (which does not). </Li> <Li> The large intestine also has microvilli on the surface of its colonocytes (alternative name for enterocytes). </Li> </Ul> <Li> The small intestine tract: This is where absorption takes place .
