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 simple epithelial tissue is a closed network of flat epithelial cells. These are located on the basal membrane. Simple epithelial tissue is found in the alveolar epithelium (pulmonary alveolus), the endothelium (lining of blood vessels and lymph vessels) and the mesothelium (lining of the body cavities). Medically, the simple epithelium is further divided into two types:
