The blood in the coronary veins then drains into the coronary sinus.

然后，冠状静脉中的血液排入冠状窦。

There's also a tiny third opening into the right atrium called the coronary sinus, which collects blood from coronary vessels returning from the myocardium.

右心房还有第三个微小的开口叫冠状窦，以收集从心肌返回的冠状静脉血液。

The coronary sinus sits in a groove at the back of the heart, and it collects the deoxygenated blood from the coronary circulation and then returns it to the right atrium.

冠状窦位于心脏背面的凹槽中，从冠状动脉循环中收集脱氧的血液，然后将其送回右心房。
