Morphology
The meaning is directly and compositionally derived from 'thoracic' (relating to the chest) + 'aorta' (the main artery from the heart), so a learner who knows both words can infer 'the aorta located in the chest'. Although anatomical, this is a straightforward noun phrase rather than an idiom, and the same compositional logic occurs across languages, making it transparent.
Etymology
Thoracic aorta combines aorta, the body's 'main artery', with thoracic, meaning 'chest', so it names the part of the main artery that runs through the chest and gives blood to the chest organs.
