Answer
The following are the subdivisions of the aorta: the ascending aorta; the arch of the aorta; the thoracic aorta, and the abdominal aorta.
Work Step by Step
The ascending aorta sprouts the left and right coronary arteries which supply the muscles of the
heart
The arch of the aorta gives rise to the brachiocephalic arterial trunk. This trunk gives of the following branches:
Right and left common carotids ; these arteries supply the neck and the sides of the head
Right and left subclavian--supply the upper limbs.
The thoracic Aorta: The thoracic aorta has many branch arteries that supply the following areas: the pericardium, the bronchi, esophagus, mediastinal structures, intercostal and chest muscles, upper abdominal muscles, and upper surface of the diaphragm.
The abdominal aorta gives off many branches that supply blood to lower abdominal structures, the pelvic organs, and the lower limbs. Some specific structures are the inferior surface of the diaphragm; abdominal muscles; gastrointestinal organs and glands; spleen; kidneys; liver; adrenals; pancreas; genitourinary structures and glands ( bladder, ovaries, testes), and lower limbs
