PRINCIPLE ARTERIES ANATOMYThe aortic artery is the primary artery, creating through branches the remaining arteries throughout the human body. The aorta leads from the left ventricle arching toward the left barely above the heart and then descends through the thorax and into the abdomen.
The branches which break from the aortic artery are responsible for the delivery of oxygenated blood throughout the entire human body. When the left ventricle goes into a period of contraction, blood is forced through the arteries included in systemic circulation. This process is repeated every time the heart beats.
