Aorta. The aorta is the largest blood vessel in the body. It is an artery that directly arises from the heart itself and descends through the thorax and into the abdomen. All the arteries of the body, save the pulmonary arteries, stem from the aorta or one of its main branches.
Ambulance Services. Ambulance Services Overview The Office of Emergency Medical Services licenses all ambulance services that are based in or regularly operate in Massachusetts, and certifies ambulance vehicles. Ambulance services may be private for-profit enterprises, private non-profit entities, municipally run or volunteer services.

Often, they are a high-cost prequel to expensive emergency room visits. Joanne Freedman's two-block ambulance ride was billed at $900. It was crazy.
