Document Summary

Circulatory system ch 23b systemic arteries general arterial flow out of the heart. Oxygenated blood is pumped out of left ventricle into ascending aorta, from which 2 branches emerge: left coronary artery, right coronary artery. 3 arterial branches emerge from the aortic arch: brachiocephalic trunk. Right subclavian arteries: left common carotid artery, left subclavian artery major vessels of external head & neck. Left & right common carotid arteries supply most of the blood to the head & neck. At the superior border of the thyroid cartilage, they divide into external & internal carotid arteries. Right & left subclavian arteries supply blood to upper limbs. As subclavian artery passes over lateral border of first rib, name changes to the axillary artery. As axillary artery passes the inferior border of the trees major muscle, name changes to brachial artery. In the cubital fossa, brachial artery bifurcates into the ulnar & radial arteries.
