===Systemic Circulation===
===Systemic Circulation===
Arteries of the systemic circulation transport oxygenated blood from the left ventricle to organs and tissues of the body.
====Aorta====
====Aorta====
The aorta is the start of the systemic circulation. It begins at the left ventricle, from which it is separated by the aortic valve. The initial portion is enlarged, forming the 'aortic bulb', from which the '''coronary arteries''' supplying the heart wall arise. The aorta ascends to the right of the pulmonary trunk, then turns dorsocaudally and to the left in a U-shape to become the '''aortic arch'''. The '''ascending aorta''' continues caudally to the level of the 6th thoracic vertebra, at which point it becomes the '''descending aorta'''.
