Morphology

plexus + choroideus

This is a technical Latin anatomical term: while 'plexus' (a network of vessels/nerves) gives a vague idea of a network, 'choroideus' is not a common English word and its specific anatomical referent (choroid plexus in the brain producing cerebrospinal fluid) is not derivable by a B1 learner from the parts. The specialized medical meaning requires domain knowledge rather than ordinary compositional inference, so the expression is opaque to typical learners.

Etymology

Plexus choroideus comes from words that make a simple picture: plexus means a woven 'network' and choroideus refers to a thin 'membrane' near the brain's small spaces. Imagine a small net of blood vessels that makes the liquid that bathes the brain and helps control its pressure, so the name fits the structure's job.
