Morphology

vesicula + umbilicus

If a learner knows the constituents (vesicula ≈ ‘vesicle’, a small sac, and umbilicus ≈ ‘navel/umbilical’), they can infer this refers to a small sac associated with the umbilical region, so the basic referent is compositional. However, the precise embryological function (a temporary circulatory role until the heart functions) is specialized medical information not fully predictable from the parts alone, so the transparency is only partial.

Etymology

Vesicula umbilicus comes from the Latin words vesicula meaning 'little sac' and umbilicus meaning 'navel'. It names a tiny sac near an embryo's navel that carries blood until the heart starts, so the phrase now means a temporary early blood-carrying structure.
