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 primary function of the aortic arch?

• To regulate blood pressure

• To connect the left ventricle to the pulmonary artery

• To connect the ascending aorta to the thoracic aorta

• To supply blood to the lower extremities

What does the brachiocephalic trunk split into?

• Right common carotid artery and right subclavian artery

• Thoracic aorta and abdominal aorta

• Common carotid artery and subclavian dextra artery

• In front of the trachea

• To the right of the trachea

• Directly behind the trachea

Which artery supplies the left shoulder and arm?
