What is the BEST name for an epithelium that is one layer of flat cells (i.e., width of cells is greater than the height) that lines blood vessels?

Question

BlackTom AI · Accepted Answer

The question asks for the best name of the epithelium that lines blood vessels and is composed of a single layer of flat cells whose width exceeds their height.
Option 1: Urothelium. This type of epithelium lines the urinary tract (bladder, ureters) and is typically a stratified, transitional epithelium, not a single layer of flat cells, so it is incorrect here.
Option 2: Simple stratified epithelium. The term is a contradiction: 'simple' means one cell layer, while 'stratified' implies multiple layers. Since we’re given one layer, this option is conceptually mismatched and therefore not appropriate for lining vessels.
Option 3: Endothelium. This is the lining of blood vessels and lymphatic vessels, composed of a single layer of flattened (squamous) cells with a width greater than its height, which matches the description precisely.
Option 4: Nonciliated simple columnar epithelium. This epithelium consists of a single layer of tall, column-like cells, which are not flat; thus it does not fit the description of a single layer of flat cells lining vessels.
Option 5: Mesothelium. Mesothelium lines the serous cavities (peritoneum, pleura, pericardium), not the interior surface of blood vessels, so it is not the correct lining for vessels.
In summary, the descriptor of a single layer of flat, wide cells lining blood vessels aligns with the endothelium, while the other options describe epithelia that either are not single-layered squamous, not located in vessels, or have a different cellular shape.
