Quizplus · Accepted Answer

The submucosa is the layer of the digestive tube that contains blood vessels, lymphatic nodes, and nerves. The serosa is the outermost layer of the digestive tube that secretes a lubricating fluid to reduce friction as organs move against each other. The adventitia is a similar layer, but does not secrete any fluid and is found in organs that are not covered by a serosa, such as the esophagus.
