Key insights

🩸The ascending aorta supplies blood from the left ventricle and arches to form the aortic arch.

❤️The external carotid artery branches off the common carotid artery and supplies blood to external structures of the head and face.

🔀The left gastric artery is a branch of the celiac trunk and supplies blood to the stomach.

🔎The left internal thoracic artery supplies the diaphragm, while the left posterior intercostal arteries supply the intercostal muscles.

🦠The splenic artery supplies blood to the spleen, an important organ in the immune system.

Q&A

What does the left internal thoracic artery supply?

—The left internal thoracic artery supplies blood to the diaphragm.

What is the function of the left posterior intercostal arteries?

—The left posterior intercostal arteries supply blood to the intercostal muscles.

What organ does the splenic artery supply?

—The splenic artery supplies blood to the spleen.
