Ducts and Blood Vessels
Notes
Ducts are relatively simple tubular structures which are (usually) easily distinguished from blood vessels by their conspicuous cuboidal epithelial lining. (Blood vessels, of course, are lined by simple squamous endothelium.)
This image from the esophageal submucosa includes small examples of a duct, a vein, and an artery.
Click anywhere on the image to identify the structures. (Depending on your browser, simply "hovering" over an area may produce a label.)
