Morphology
The noun phrase is a straightforward adjective + noun combination: 'lumbar' specifies the lower back region and 'vein' denotes a blood vessel, so the meaning 'a vein in the lumbar/lower back area' is directly derivable from the parts. This kind of anatomical naming is compositional and common across languages, so a B1 learner who knows both constituents would understand it.
Etymology
The name lumbar vein refers to a blood vessel in the lower back. Here lumbar means 'lower back' and vein means a tube that takes blood back to the heart, so the name shows it carries blood from the lower back.
