Main arteries of the trunk

This video tutorial explores the blood supply to the trunk, focusing on the major arteries such as the aorta, celiac trunk, and mesenteric arteries. It begins with an overview of the circulatory system, emphasizing the role of arteries in transporting oxygenated blood. The tutorial then delves into the aorta's structure, its branches, and their functions. Clinical notes on conditions like atherosclerosis and aneurysms are also discussed, providing a comprehensive understanding of arterial health.

What is the primary function of arteries in the circulatory system?

• To exchange gases and nutrients with tissues

• To store blood for emergencies

• To transport oxygenated blood away from the heart

• To carry deoxygenated blood to the heart

Which part of the aorta receives blood directly from the left ventricle?

• Descending aorta

• Thoracic aorta

• Ascending aorta

• Arch of the aorta

What are the two primary branches of the left coronary artery?

• Right and left coronary branches

• Posterior and anterior interventricular branches

• Circumflex and anterior interventricular branches

Which artery supplies the right upper limb?

• Brachiocephalic trunk

• Right subclavian artery

• Right common carotid artery

• Left subclavian artery

What is the function of the posterior intercostal arteries?

• Supply blood to the ribs and muscles that move them

• Supply blood to the heart

• Supply blood to the digestive organs

• Supply blood to the brain

Which artery is the first major branch of the abdominal aorta?

• Superior mesenteric artery

• Inferior mesenteric artery
