The aorta receives blood from the pumping action of the heart. More specifically, from the left ventricle.
Heart receive the blood from ascending aorta. You get right and left coronary arteries from the aorta, to supply blood and nutrients to your heart.
arteries
blood travels from the ascending aorta to the aortic arch to the descending aorta
The myocardium receives blood from the coronary arteries.
If you are talking about where does the blood inside the descending aorta come from, it comes from the aortic arch, which comes from the ascending aorta. If you are talking about the blood that nourishes the tissues of the aorta, it is the vasa vasorum.
Blood goes in this order... Right Atrium -> Right Ventricle -> Lungs -> Left Atrium -> Left Ventricle -> Ascending Aorta -> Descending Aorta. So neither pump blood to the the Left Ventricle but the Left Ventricle pumps blood to the ascending aorta.
The aorta supplies blood to the heart.

The left ventricle pumps blood to the aorta
Left ventricle pumps blood through the aorta, which then goes through the brachiocephalic trunk, and then through the subclavian artery and then into your axillary artery Sierra Q
no that would reverse the flow of blood. blood is squeezed out of the left ventricle through the aorta.
