directed anteriorly, and dorsally to the right bronchus, between the 

 right bronchus and the right lung. The right and the left coro- 

 naries are given off from the common aorta; they have been dis- 

 cussed. There is next given off the left brachio-cephalic or brachio- 

 cephalic sinister artery (Fig. 6iB, No. K, 10), which is just above the 

 border of the base of the heart. This artery passes upward and slightly

forward, over the center of the inferior larynx. Just beyond this 

 point the subclavian artery is given off; this artery later becomes the 

 axillary and the axillary the brachial artery. Then there is given 

 off the anterior and the posterior thoracic arteries; and finally, the 

 pectoral, which supply the pectoralis muscles and later terminate 

 in the carotid, the vertebral, and the cervical arteries. The carotid
