An adult body contains over 60,000 miles of vessels, which can wrap around the world two and a half times. The vessel branching off of the heart is largest artery in our body and is known as the aorta. The aorta supplies oxygenated blood to our body. The aorta runs along the midline of our body and has many other vessels that stem from it to deliver the blood to a specific location. The aorta has several different names, depending on the location in the body. As it comes off of the heart at the left ventricle it is called the ascending aorta. It is located in the anterior mediastinum and is approximately three to five centimeters wide. In the superior mediastinum, at the peak of the aorta, it turns to resemble and upside down U and become the aortic arch. As it pass behind the heart and starts to go down into the thoracic cavity it becomes the descending aorta, more specifically, the thoracic aorta. The diameter of the thoracic aorta is about two and a half centimeters wide. Once the aorta reaches the diaphragm and passes into the abdomen it converts the abdominal aorta. The abdominal aorta is about two centimeters wide. The thoracic aorta runs for about twenty centimeter and the abdominal aorta extends for about fifteen centimeters long.
