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.
The tunica interna is the innermost lining of the blood vessel. It is lined by endothelium, which is almost always simple squamous epithelium, and its underlying connective tissue. In arteries a layer of elastic tissue called the internal elastic membrane marks the outer boundary of the tunica interna.2.he tunica interna is the innermost lining of the blood vessel.
