Morphology

vena + cava

Both constituents are literal anatomical terms (vena = vein; cava = major/hollow vein), so the compound denotes a (large) vein that carries blood to the heart. The phrase is non-idiomatic and compositional (and appears across languages in medical terminology), so a learner who knows the parts can infer the basic meaning.

Etymology

Vena cava comes from the Latin words vena meaning 'vein' and cava meaning 'hollow', so the phrase gives the picture of a very large hollow vein. That's why the name means 'a large hollow vein that carries blood back to the heart'.
