Which arteries carry low oxygenated blood to the lungs?

The pulmonary arteries are responsible for carrying low oxygenated blood from the right side of the heart to the lungs. This process is a crucial part of the circulatory system, as it allows for the exchange of carbon dioxide for oxygen in the lungs. Once in the lungs, the blood releases carbon dioxide and absorbs oxygen during respiration. This oxygen-rich blood then returns to the heart through the pulmonary veins, where it can be circulated throughout the body.

In contrast, the aorta distributes oxygenated blood from the heart to the rest of the body. The coronary arteries supply blood to the heart muscle itself, while the carotid arteries provide blood to the brain. Therefore, the role of the pulmonary arteries in transporting deoxygenated blood specifically to the lungs sets them apart as the correct answer to the question.
