Right Coronary Artery Function
右冠状动脉的功能
The coronary circulation is responsible for nourishing the heart during its tireless effort in pumping blood around the body. The focus of this video is the right coronary artery, which you can find here highlighted in green on this image of the anterior view of the heart.
冠状动脉循环负责在心脏持续向全身泵血的过程中滋养心脏。这个视频重点讲解右冠状动脉，见心脏前视图图像上的绿色部分突出显示的结构。
Along with the left coronary artery, the right coronary artery branches off of the ascending aorta. The right coronary artery passes through the atrioventricular groove to the right side and continues on to the posterior surface of the heart.
右冠状动脉与左冠状动脉均起自升主动脉。右冠状动脉穿过房室沟到右侧，并继续延伸到心脏的后表面。
It supplies the right atrium, the majority of the right ventricle, the portion of the left ventricle that communicates with the diaphragm (areas of the interatrial and interventricular septa), the sinoatrial node in around sixty percent of the population, and the atrioventricular node in general.
一般而言，它供应右心房、大部分右心室、与膈肌连接的左心室部分（房间隔和室间隔区域），约60%的人群的窦房结以及房室结。
This artery further divides into several branches including the sinoatrial nodal branch, the right marginal branch which runs to the right margin of the heart, and the atrioventricular nodal branch which supplies the atrioventricular node at the junction of the four heart chambers within the septae on the posterior side of the heart.
右冠状动脉进一步分为多个分支，如窦房结支、延伸至心脏右缘的右缘支，以及在心脏后侧的间隔内，心脏四腔交界处供应房室结的房室结支。
Lastly, a posterior interventricular branch runs along the posterior interventricular groove.
最后，后室间支沿后室间沟走行。
