Morphology

accessory + hemiazygous + vein

The noun phrase is partly compositional: 'accessory' + 'vein' clearly yields the idea of an additional blood vessel. However 'hemiazygous' is a technical anatomical label (missing from the provided dictionary entry) and the precise anatomical relationships and drainage pattern cannot be predicted from the constituent words alone, so the expression is only partially transparent to learners.

Etymology

Accessory hemiazygous vein paints a simple picture: accessory means 'extra', hemiazygous points to a vein on one side of the chest, and vein is a blood 'road'. It is like a small side road that collects blood from the upper left spaces between the ribs and joins the big 'main vein' at the back of the chest, which is why the name describes its job.
