Morphology

renal + pelvis

Both constituents are directly descriptive: 'renal' means 'related to the kidneys' and 'pelvis' (in the medical sense) denotes a funnel-like structure that collects urine, so their combination transparently yields 'the kidney's funnel that collects urine.' This adjectival-noun composition is a straightforward, cross-linguistically common pattern and would be understandable to a B1 learner who knows the two words.

Etymology

Renal pelvis comes from words for the kidney and a small basin: renal means 'about the kidney' and pelvis was used like a 'basin' or 'bowl'. So the name gives a clear picture of a funnel or bowl inside the kidney that collects urine before it goes down the tube to the bladder.
