Morphology

vena + hemiazygos + accessoria

This is a Latin medical name where 'vena' (vein) and the idea of 'accessory' are transparent, but 'hemiazygos' and 'accessoria' are specialized/Latinized forms not in general vocabulary; 'hemiazygos' can be morphologically analyzed (hemi‑ = half, azygos = a specific vein) but that requires anatomical knowledge. Because part of the meaning is compositional (an accessory vein) but the specific reference and technical morphology are not predictable for an average B1 learner, the expression is only partially transparent.

Etymology

The noun vena hemiazygos accessoria literally names the vein: vena means 'vein', hemiazygos shows it is the left or 'half' side of the main azygos vein, and accessoria means 'extra' or 'accessory'. So imagine a small left-side vein that joins the main azygos vein and drains blood from the spaces between the ribs, which is why the name fits what it does today.
