Morphology
The meaning is directly and literally built from 'descending' (moving downward) + 'aorta' (the main artery), so a learner who knows both words can infer it denotes the part of the aorta that goes downward. Although anatomical, the spatial compositional pattern is transparent and corresponds to similar constructions cross-linguistically, making it easily comprehensible to B1 learners who know the constituents.
Etymology
Descending aorta is the name for the main artery, aorta, that descends or 'goes down' from the heart. Imagine a strong river carrying blood down through the chest and belly to the 'lower body', so the name means the part of the aorta that goes down.
