Aorta Anatomy – USMLE 1

Now, if I were to open my chest again and this time remove my lungs and other organs, you would be able to see the aorta, the largest artery of the human body right here.

Leaving the heart is the ascending part of the aorta.Then the aortic arch and then the descending part of the aorta.

In a cross section like this, we can see that aorta has a very thick wall and a large lumen to facilitate the blood flow to all the important organs, such as the brain over here, through the carotid arteries.
