Aortenbogen

The video tutorial explains the anatomy of the aorta, starting from the aortic valve and left ventricle. It describes the ascending aorta, the aortic arch, and the thoracic aorta. The aortic arch gives rise to three major branches: the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery. The brachiocephalic trunk is unique to the right side, while the left common carotid and subclavian arteries arise directly from the aortic arch. These branches supply blood to the head, neck, and upper extremities.

What is the function of the aortic arch in the circulatory system?

List the three important branches that emerge from the aortic arch.

Describe the location and significance of the brachiocephalic trunk.

How does the left common carotid artery differ from the right common carotid artery?

Explain the pathway of the subclavian sinistra artery.
