Morphology

intra-arterial = arterial (semi-transparent) = intra + arterial

The parts 'intra-' (within) and 'arterial' (relating to arteries) are semantically clear but the term is technical/medical and may be unfamiliar to general learners.

Etymology

Intra-arterial comes from the parts intra- meaning 'within' and arterial from 'artery', the blood vessel that carries blood from the heart. So intra-arterial describes something that happens 'inside an artery', which is why doctors use it for treatments or measurements placed directly in that vessel.
