The posterior aorta (Fig. 63, No. 2) passes backward along the 

 inferior part of the bodies of the dorsal and lumbo-sacral vertebrae. 

 In the thoracic cavity it lies dorsal to the esophagus. It gives 

 branches (esophageal) only to the esophagus during its passage as far 

 as the seventh dorsal vertebra. Following this point there are given 

 of several pairs of arteries which divide into a superior and an infe- 

 rior branch. The superior branch extends upward and anastomoses 

 with branches of the vertebral artery and other twigs coming from 

 the intercostal arteries. These latter arteries given off are small 

 dorsal arteries. The inferior branches extend downward between 

 the ribs and supply the intercostal muscles. The intercostal arteries
