luminal
Inside the tube
Luminal relates to the lumen—the interior space of a tubular structure.
In medicine and biology, luminal describes things occurring within or facing toward that space: the luminal surface of a blood vessel, luminal contents of the intestine.
The word appears in technical contexts discussing how substances interact with the inner walls of organs, ducts, or cells.
