Morphology

lumbar + artery

The meaning is directly compositional: 'lumbar' names the lower‑back region and 'artery' is a blood vessel, so a learner can infer it is an artery in the lumbar area. This noun‑noun medical term follows regular English formation and has clear equivalents in other languages (e.g. arteria lumbar), making it easily understandable to a B1 learner who knows both constituents.

Etymology

The compound noun lumbar artery puts together lumbar, meaning 'lower back', and artery, a 'blood vessel', so it names a vessel in the lower back. That's why the term refers to the arteries that give blood to the back, its muscles, and the wall of the belly.
