Aortic Arch

We've learned that the big tube leaving the heart is called the aorta, and the first part of the aorta that goes up is called the ascending aorta.

After the ascending aorta goes up, it turns toward the middle of your body by your trachea.
That curved part where it turns is called the aortic arch.

There are some smaller tubes that come out of the aorta at the arch and go up toward the neck and head, and then the large aorta tube turns to go downward.
