The lumen is the space within the blood vessel (or within any tubular structure).
The lumen is the inner open space or cavity of a tubular organ, such as a blood vessel or an intestine
by dilating the blood vessel with the introduction of larger and larger stiff catheters through the narrowed space. The complications that resulted from this approach led researchers to develop ways to open the vessel with smaller devices
The method for achieving warp speed in Star Trek is to warp the space around the vessel and leave the vessel in a pocket of normal space. It contracts space time in front of the vessel and expands the space time behind it.
Intraluminal refers to something situated within the space or lumen of a tubular structure in the body, such as a blood vessel or intestine. It is often used to describe things like catheters or obstructions that are inside a tubular space.
Tolerance
The internal space of the endoplasmic reticulum is called the cisternal space, or lumen, which is part of the "rough endoplasmic reticulum." The lumen is the staging area where the final modifications of protein synthesis take place, and its quality is analysed before releasing it for transportation to it's intended destination.
