vasovagal = vagal (semi-transparent) = vaso + vagal

The form combines the medical combining form 'vaso-' with 'vagal' in a straightforward way, but both elements are technical and may be unfamiliar to general learners.

Etymology

Vasovagal comes from two parts: vaso- 'vessel', as in vessel, and vagus 'wandering', as in vagabond. So vasovagal describes the wandering vagus nerve acting on blood vessels, which can cause a sudden drop in blood pressure or fainting.
