Detailed explanation-3: -Answer and Explanation: All arteries of systemic circulation branch from the b. aorta. This is the first artery that arises from the left ventricle, and it branches to supply all of the tissues in the body.

Detailed explanation-4: -ascending aorta. right and left coronary arteries arise as the aorta leaves the heart and carry blood into the coronary circuit. arch of the aorta. left and right common carotid arteries. subclavian arteries. descending aorta.
