What is the first artery to branch from the aorta?
Answer:
Subclavian Artery

The wiki reference above doesnt provide plenty info. The subclavian isn't correct. The inital arteries departing from the mainstem aorta, immediately exiting the aortic root, are the coronoary arteries supplying the cardiac muscle itself. Hope this help, cheers.
The first arteries to branch from the ascending aorta are the coronary arteries. Whether it is the right or left may change from one body to the next.
When this sound out is asked, they are usually asking what is the first branch of the aortic arch, where it starts to bend down towards the foot. The answer to this question is the brachiocephalic artery (used to be call the innominant, or nameless artery.) The brachiocephalic next branches into the right subclavian and right common carotid arteries.
remember 1) other use right or left when answering anatomy question if there is a right or departed. 2) No two bodies are the same and in that are always variation. Things may look different inside a patient than they do within the book. A good anatomy book will administer you the most common variation also.
PahD is absolutely correct!
