not enough oxygen poor blood would enter the heart
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
no that would reverse the flow of blood. blood is squeezed out of the left ventricle through the aorta.
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.
AOrta
The Aorta and the Vena Cava
Aorta
the aorta that fluid that enters
when it just come out from the heart at the aorta
blood travels from the ascending aorta to the aortic arch to the descending aorta
Oxygenated blood flows from the lungs to the left atrium contractions (heart muscle) cause the blood to leave the atrium and enter the left ventricle. Further contraction causes the blood to leave the atrium and enter the aorta.

Oxygenated blood from the lungs enters the left atrium. The blood then moves from there to the left ventricle, aorta, and on the rest of the body.
