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. 

 Tin- ri-'ht 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
