Morphology

atrioventricular + trunk

The term combines 'atrioventricular' (involving the atria and ventricles) with 'trunk' (a main stem or central structure), so a learner who knows both constituents can infer it denotes a principal anatomical structure connecting or relating the atria and ventricles. However, the specific electrophysiological role as a bundle of conducting fibers transmitting impulses is specialized medical information not fully predictable from the parts, making the expression only partially transparent.

Etymology

Atrioventricular trunk paints a clear picture: a main trunk that carries an electrical message from the upper chambers (atria) down to the lower chambers (ventricles). So, because this bundle really 'sends a signal' that makes the ventricles 'contract', the name explains its job in the heartbeat.
