So let's start with how the blood would normally pump through the circulatory system:

1. Circulated blood enters heart through the vena cava into the right atrium.
2. The right atrium contracts and pumps the blood through the tricuspid valve and into the right ventricle.
3. The right ventricle then pumps blood through the pulmonary artery into the lungs.
4. Oxygenated blood then flows through the pulmonary vein and into the left atrium.
5. Oxygenated blood then pumps through the mitral valve and into the left ventricle.
6. The left ventricle contracts and sends blood through the aortic arch on its way to all parts of the body. At this point, there are a few options for the blood flow: blood can be pumped
•through the carotid artery and into the brain.
•through the auxiliary arteries and into the arms.
•through the aorta and into the torso and legs.
7. Blood will then move through the arteries, then through capillaries, and then return through the veins.
8. Deoxygenated blood (blood without oxygen) will then return to the heart.
9. The cycle repeats

However in our case we have a blockage at T5 of the Aorta. The ...
