Morphology

inferior + vena + cava

The meaning is directly compositional: 'inferior' = lower and 'vena cava' = a major vein to the heart, so a learner who knows these constituents can infer it denotes the large lower body vein that returns blood to the heart. Anatomical naming is systematically built from such modifiers and this structure (lower + major vein) is cross-linguistically common, making the term transparently interpretable to learners who know the parts.

Etymology

Inferior vena cava comes from words that describe its place and shape: inferior means 'lower', vena means 'vein', and cava means 'hollow'. So the name describes a large hollow vein low in the body that carries blood up to the heart.
