Clinical Anatomy For Dummies. The tissues of the pectoral girdle need oxygen. So a complex series of arteries supplies blood flow through the shoulder, upper arm and chest area. And because the axilla includes several important lymph nodes, that lymph has to flow.
In fact, there are two main coronary arteries that branch from the ascending aorta, known as the left and right coronary arteries. In essence, the left main coronary artery supplies the left atrium, interventricular septum, left ventricle and the anterior wall of the right ventricle.rom here, it curls around towards the inferior surface of the heart, forming the posterior interventricular branch, more commonly known as the posterior descending artery (PDA). The PDA runs along the posterior interventiculas sulcus, to supply blood to the walls of both the left and right ventricle.
