Aortic Arch Anatomy- Branches- Function
主动脉弓解剖-分支和功能
In order to understand its anatomy, let’s briefly discuss the anatomy of the whole aorta, the largest artery in the human body and directly connected to the heart.
为了解主动脉弓的解剖学，我们简单讨论一下整个主动脉的解剖结构，主动脉是人体内最大的动脉，与心脏直接相连。
After starting at the aortic valve, the ascending aorta winds towards the head, becomes the aortic arch or the transverse aorta as it makes a rainbow shape over the superior aspect of the heart, and then moves in an inferior direction through the chest and abdomen.
升主动脉从主动脉开始后，向主动脉头部缠绕，在心脏上部形成彩虹状的主动脉弓或横主动脉，然后向下穿过胸部和腹部。
At the left subclavian artery, it becomes the thoracic aorta. After the thoracic aorta comes the abdominal aorta.
在左锁骨下动脉处，主动脉弓成为胸主动脉。然后胸主动脉移行为腹主动脉。
You can see the aorta with the aortic arch highlighted in green and the full aorta pictured without its many branches.
你可以看到用绿色突出显示的主动脉和主动脉弓，图上的完整主动脉没有标出相应的分支。
The aortic arch or transverse aorta gives three branches which supply the head and upper limbs.
主动脉弓或横主动脉有三个分支，分别供应头部和上肢。
The first branch of the aortic arch is the brachiocephalic artery, which splits further into the right common carotid and right subclavian arteries.
主动脉弓的第一个分支是头臂动脉，它进一步分支为右颈总动脉和右锁骨下动脉。
The other two branches that come out of the aortic arch are the left common carotid artery and the left subclavian artery.
从主动脉弓发出的另两个分支是左颈总动脉和左锁骨下动脉。
