The subclavian arteries carry blood to the arms. The branching from the aorta on the right side of the body is as follows :
Aorta- brachiocephalic- subclavian- axillary (located in your upper arm). From those, you have lots of branches.
In the left side, the aortic branching is slightly different.
Aorta-left subclavian (directly)-axillary
The aorta has a third branch on the arch to the left common carotid, which is the reason that the left side doesn't have the brachiocephalic branch that the right side does. The brachiocephalic branch is just the right subclavian and common carotid running together before a branching point.
Hope this helps!

How can you trace a drop of blood from the pulmonary artery to the right radial artery?
Why would you want to do that. You would have to cut open the heart and watch the blood move from the pulmonary artery through the heart and into the right radial artery.
What does the cephalic artery do?
There is actually no such artery as the cephalic artery. There is the brachiocephalic artery which comes out of the aortic arch, and also a cephalic vein.
What is main artery?
The aorta. This leaves the heart (left ventricle) loops over (aortic arch) and becomes the descending aorta. Their are other arteries that branch off along the way, carotid, brachial, etc. then the aorta splits into the femoral arteries.
What artery branches off left brachiocephalic artery?
The brachiocephalic artery divides into the right common carotid artery and the right subclavian artery.
Is the brachiocephalic artery longer on the left side than on the right?
Trick question.... you only have 1 brachiocephalic trunk. It comes off the right side of the aortic arch (right side from anatomical position, or the patient's perspective) and immediately splits into the subclavian artery and the common carotid artery. On the left side of the arch the subclavian and common carotid branch directly off the aortic arch. Hopefully this makes sense.
