Look for a similar connected chain of nuclei lining the inside of a vein, (See Slide A28, renal artery and vein) H&E [ 2.5x, 10x, 20x, 40x-labeled]; AF [ 10x, 20x, 40x]; H&E [ 20x, 40x, 40x, 40x]. The inner lining of the blood vessels, called the endothelium is a simple squamous epithelium. The lining may appear interrupted in the section, in part because the cytoplasm between nuclei is drawn out so thinly. In life, of course, the membrane is unbroken and lines the vessel completely. The simple squamous epithelium that lines the abdominal cavity has the special name of mesothelium.

2. Simple Cuboidal Epithelium lines the ducts of many glands, kidney tubules and the follicles of the thyroid gland, Slide B-68 [ 2.5x, 10x, 20x, 40x-labeled]. Observe the cuboidal cells lining many of the renal tubules. Here you can find tubular cells in which the height of the cell is approximately the same as the basal diameter of the cell.
