Control of the thoracic circulations

We have decided to raise questions rather than provide answers, realizing that the thoracic circulations have very complex interconnecting control system relationships. For example, parts of the 6th vascular arch embryologically form the pulmonary circulation, which in turn interface with the developing airways, themselves a derivative of the foregut. This alone begs the question of expectations with respect to control systems common to gut, and the pulmonary, bronchial and lung lymph systems. Since the 6th arch system joins with evaginations from the folding vascular tube destined to be the heart, would the enveloping innervation also affect the control of cardiac function? And finally, both the coronary and the bronchial vessels do constitute some sort of vasa vasorum to the myocardium and indeed, the major pulmonary vessels, as well as in the case of the bronchial vessels, to the airways, with secretory mechanisms driven in part by non-adrenergic, non-cholinergic mechanisms.
