The aorta is the major blood vessel that feeds blood to the body. A thoracic aortic aneurysm may also be called thoracic aneurysm and aortic dissection (TAAD) because an aneurysm can lead to a tear in the artery wall (dissection) that can cause life-threatening bleeding.
COC offers the Associate degree in two areas: Associate of Arts (AA) and Associate of Science (AS). An AA/AS is typically achieved in two years of full-time attendance, earning a minimum of 60 units credit.
This said, the computation is simple: A single AA Degree is worth 60 semester units; a second AA Degree is worth an additional 60 semester units, for a total then of 120, and so on. Two AA's then are worth one BA, while four AA's are worth two BA's (4 x 60=240 units).
