Understanding 动脉 (dòng mài)
动脉 refers specifically to arteries, the blood vessels that carry oxygen-rich blood away from the heart to the rest of the body. It is a technical medical term commonly used in health and biology contexts.
Usage in Medical Contexts
动脉 often appears in discussions about cardiovascular health, such as 动脉堵塞 (artery blockage) or 动脉血压 (arterial blood pressure). These collocations are important for describing conditions and measurements related to heart function.
Common Collocations
- 动脉堵塞: artery blockage, used when blood flow is obstructed.
- 动脉血压: arterial blood pressure, a key health indicator.
- 动脉硬化: arteriosclerosis, the thickening or hardening of artery walls.
Tips for Learners
动脉 is a noun and usually appears in formal or scientific contexts rather than everyday conversation. It contrasts with 静脉 (jìng mài), which means vein. Remember that 动 means "to move" and 脉 means "pulse," reflecting the artery's role in carrying the pulse of blood flow.
Avoid confusing 动脉 with veins or capillaries, which have different functions and terms.
