Notes on Usage

• Technical Term: "Vận mạch" is a specialized scientific and medical term. It is almost exclusively used in technical contexts such as biology, anatomy, physiology, and medicine. It is not used in everyday conversation.
• Word Formation: The word is a Sino-Vietnamese compound. "Vận" implies movement or operation, and "mạch" means vessel (typically blood vessel). Thus, it directly translates to "vessel-moving" or "vessel-operating."
