Oxygenated blood leaving the heart flows into the aorta, one of it's earliest branches is the '''subclavian artery''' which supplies blood to the forelimb, neck and cervicothoracic junction. It moves round the cranial border of the first rib and enters the limb via the axilla; at this point it changes it's name to the '''axillary artery'''. It is this vessel that supplies the forelimb. | Oxygenated blood leaving the heart flows into the aorta, one of it's earliest branches is the '''subclavian artery''' which supplies blood to the forelimb, neck and cervicothoracic junction.
