Morphology

internal + organ

The meaning is directly and compositionally derived from 'internal' (located within) + 'organ' (a body part performing a function); a learner who knows both words will infer it refers to an organ inside the body. This is a standard adjective+noun combination common across languages and medical contexts, so it is immediately comprehensible to B1 learners.

Etymology

Internal organ combines internal and organ: imagine your body as a house and an internal organ is like a hidden pump or heater working behind the walls. So, it means 'an important organ kept inside the body', such as the 'heart' or 'liver'.
