Final answer:
The three major coronary arteries are the left coronary artery, the right coronary artery, and the circumflex artery.
Step-by-step explanation:
The three major coronary arteries are the left coronary artery, the right coronary artery, and the circumflex artery.
The left coronary artery distributes blood to the left side of the heart, the left atrium and ventricle, and the interventricular septum. It gives rise to the circumflex artery which follows the coronary sulcus to the left and eventually fuses with small branches of the right coronary artery.
The right coronary artery distributes blood to the right atrium, portions of both ventricles, and the heart conduction system. It also gives rise to the posterior interventricular artery on the posterior surface of the heart.
