Early proximal tubule
WebIt has further been shown that the effect of Ang II to increase proximal tubular chloride and water reabsorption decreases by about 75 per cent following renal denervation and only … The most distinctive characteristic of the proximal tubule is its luminal brush border. The luminal surface of the epithelial cells of this segment of the nephron is covered with densely packed microvilli forming a border readily visible under the light microscope giving the brush border cell its name. The microvilli greatly increase the luminal surface area of the cells, presumably facilitating their reabsorptive function as well as putative flow sensing within the lumen.
