HUMAN ANATOMY. 



At first the oesophagus lies behind the trachea on the prevertebral fascia, the 

 lobes of the thyroid gland touching it on either side. As*it descends to the left, the 

 trachea is partly on the right. The left recurrent laryngeal nerve runs on the front. 

 The right one is in relation with only the very beginning of the gullet. The right 

 inferior thyroid artery is against it. On the right also a chain of lymphatics in the 

 areolar tissue lies very close to it. The left carotid and subclavian arteries are very 

 near it, if not in actual contact. As may be inferred, the gullet and the aorta are

spirally entwined. The thoracic duct and the vena azygos major are in contact with 

 it from the diaphragm to above the roots of the lungs, the former lying between it 

 and the aorta as far as the level of the aortic arch, the latter, at first more posterior 

 than the duct, passing as it rises behind the (^esophagus and finally arching forward 

 close to its right side. The left vena azygos, such left intercostal veins as open into 

 the azygos major, and the right intercostal arteries pass behind the gullet. The pneu- 

 mogastrics reach it in the thorax : the right after crossing the subclavian artery and
