Arteries of the thorax

This tutorial explores the arteries supplying the thorax, focusing on the aorta and its divisions: the ascending aorta, aortic arch, and descending aorta. It details the branches of each section, including the coronary arteries, brachiocephalic trunk, and subclavian arteries, and their roles in supplying blood to various parts of the body. The tutorial also covers the thoracic aorta's visceral and parietal branches, emphasizing their importance in thoracic circulation.
