- Describe the function of the areas of the heart usuallysupplied by the left coronary artery.arrow_forwardDefine each of the following external features of the heart: auricle, coronary sulcus, anterior interventricular sulcus, and posterior interventricular sulcus.arrow_forwardDr. J was performing a cardiac bypass on her 53-year-old male patient whose anterior interventricular artery was narrowed near its origin. For this procedure, she chose to use the left internal thoracic artery, leaving its origin intact and cutting its distal connection to attach it to the anterior interventricular artery just beyond the narrowed segment. This successfully restored blood flow to the anterior portion of the heart. What path does the blood take through this diverted route? Aortic arch to axillary artery to internal thoracic artery. O Aortic arch to the left subclavian to internal thoracic artery Aortic arch to left subclavian artery to pericardiacophernic artery to internal thoracic artery Aortic arch to brachiocephalic artery to internal thoracic artery Aortic arch to internal thoracic arteryarrow_forward
