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.
Medical Certification Requirements. New Federal regulations require that every commercial learner permit (CLP) holder or driver license (CDL) holder must certify to the type of commercial driving they currently perform (or expect to perform). Once we send the notification, we will cancel the CLP if the CLP holder does not re-certify within 55 days.
