Morphology

bundle + of + His

This is an eponymic medical term: 'His' is a proper name (Wilhelm His) and the phrase refers to a specialized cardiac conduction structure, information not inferable from 'bundle' + 'of' + 'His'. A B1 learner who knows the basic words would likely read it as a generic possessive ('his bundle') and would not derive the technical anatomical meaning, so the expression is unpredictable without specific medical knowledge.

Etymology

Bundle of His is named after the doctor Wilhelm His and paints an easy picture: a small bundle of fibers found by Dr. His that carries the heart's electrical signal to the lower chambers. So the phrase means 'a small group of heart fibers that send electrical messages to the ventricles'.
