Morphology
atresia = a + tresia
The prefix 'a-' means 'without', but 'tresia' is a medical combining form not known as a standalone English word, so the meaning is specialized and not derivable by an average B1 learner.
Etymology
Atresia comes from the Greek prefix a- meaning 'without' and a root tresis meaning 'a hole' or 'opening'. So atresia literally means 'without an opening', which is why doctors use it for a body passage that is closed or missing.
