Anatomy | Branches of the Aortic Arch

The video tutorial explains the structure and function of the aorta, a large elastic artery originating from the heart. It details the three main parts of the aorta: the ascending aorta, the aortic arch, and the descending aorta, and describes how blood is distributed through these sections. The tutorial also covers the branches of the aortic arch, including the brachiocephalic, left common carotid, and left subclavian arteries, and their respective roles in blood distribution. Additionally, it highlights the differences between the right and left side arteries and introduces the coronary arteries, which supply blood to the heart muscle.

What is the primary function of the left ventricle in relation to the aorta?

• To receive blood from the aorta

• To pump blood into the aorta

• To filter blood before it enters the aorta

• To store blood temporarily

Which of the following is NOT a branch of the aortic arch?

• Brachiocephalic artery

• Right coronary artery

• Left subclavian artery

• Left common carotid artery

The left subclavian artery branches into which of the following arteries?

• Right axillary artery

• Left coronary artery

• Left axillary artery

• Right vertebral artery

What happens to the left vertebral artery as it reaches the cerebrum?

• It becomes the basilar artery

• It splits into two separate arteries

• It merges with the right axillary artery

• It terminates at the cerebrum

Which artery is responsible for the difference between the left and right sides of the aortic arch?

• Left common carotid artery

• Right subclavian artery

• Brachiocephalic artery

• Left vertebral artery

Why is it important to specify 'left' or 'right' when discussing arteries?

• Because it affects the blood pressure

• To ensure accurate medical communication

• To determine the size of the artery

• Because it changes the blood flow direction

What is the role of coronary arteries?

• To supply blood to the brain

• To supply blood to the heart muscle

• To carry blood away from the heart

• To distribute blood to the limbs
