Simple squamous epithelium can be studied by looking at cells which line blood and lymph vessels. These flattened cells are called endothelial cells . The nuclei are frequently found protruding into the lumen of the vessel. Observe the numerous large blood vessels present in the periphery of this section.

These extraordinary cells were once considered to be simple lining cells with very few functional roles, other than to keep cells within the blood from leaking out of the vessels.ntroduction.
