All systemic arteries branch from the
aorta
All systemic veins drain into the
superior or inferior vena cava or coronary sinus to return to the right-side of heart
4 major divisions of aorta
ascending aorta
arch of aorta
thoracic aorta
abdominal aorta
Aorta arises from…
left ventricle (thickest chamber)
All are branches from aorta supplying
supplying arms, head, lower limbs and all viscera with O2 from the lungs
largest artery of the body
aorta
2 coronary arteries supply myocardium
ascending aorta
brachiocephalic trunk branches into right common carotid and right subclavian
left subclavian & left carotid arise independently
arch of aorta – branches to the arms & head
supplies branches to pericardium, esophagus, bronchi, diaphragm, intercostal & chest muscles, mammary gland, skin, vertebrae and spinal cord
thoracic aorta
gives rise to vertebral a. that supplies blood to the Circle of Willis on the base of the brain
subclavian arteries
Become the axillary artery in the armpit
Become the brachial in the arm
Divide into radial and ulnar branches in the forearm
subclavian branches
supplies structures external to skull as branches of maxillary and superficial temporal branches
external carotid arteries
supply eyeballs and parts of brain
internal carotid arteries
contribute to Circle of Willis
Supplies abdominal & pelvic viscera & lower extremities

Splits into common iliac at 4th lumbar vertebrae
