                                        carotid arteries and the recurrent laryngeal nerves. On the left side it is also
                                        related to the subclavian artery and the terminal part of the thoracic duct
                                        (Fig. 16).

                                        at T5 then passes downwards, forwards and to the left to reach the
                                        oesophageal opening in the diaphragm (T10). For convenience, the rela-
