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.
All states mandate that RNs be licensed, and licensure requires graduation from an approved program and passing the National Council Licensure Examination. Registered nurses in ambulance services earned a mean $33.36 per hour or $69,400 as of May 2011 according to the BLS. In ambulance services, licensed practical nurses or licensed vocational nurses provide basic medical care, typically under the supervision of doctors, registered nurses and paramedics.
