Which artery carries deoxygenated blood from the heart to the left lung?

Explanation:
The left pulmonary artery is the vessel that carries deoxygenated blood from the heart to the left lung. Pulmonary arteries transport blood from the right side of the heart to the lungs for gas exchange, and the left pulmonary artery specifically goes to the left lung. After the lungs oxygenate the blood, it returns to the heart via the pulmonary veins. The other options don’t fit because they aren’t the vessels delivering blood to the lungs: the left common carotid artery supplies oxygenated blood to the head, the ascending aorta distributes oxygenated blood to the body, and the fossa ovalis is a remnant in the interatrial septum, not a vessel.
