artery gives off an esophageal artery. The other arterial trunk given 

 off from the common aorta is the right brachio-cephahc or brachio- 

 cephaUc dexter (Fig. 61B, No. K, 18). The right brachio-cephalic 

 artery gives off the subclavian, which continues as the axillary, 

 and continues as the brachial artery. There is given off the anterior 

 and the posterior thoracic, the right carotid (Fig. 61B, No. K, 11), the 

 vertebral, and the dorsal. The last continues as the cervical. 



The pulmonary arterial trunk is given off from the conus arteriosus 

 of the right ventricle. It is guarded at its origin by three semi-lunar 

 valves similar to those of the aorta. The trunk divides into two 

 pulmonary arteries, which are short, one called the pulmonalis 

 dexter and the other the pulmonaUs sinister. The former goes to
