Final answer:
The two arteries that arise from the right coronary artery are the right marginal artery and the right posterior interventricular artery, which supply the right ventricle and both ventricles' portions, respectively.
Step-by-step explanation:
The two arteries arise from the right coronary artery is D. the right marginal artery and the right posterior interventricular artery.
Step-by-step explanation:
The right coronary artery is an essential blood vessel that supplies the right atrium, parts of both ventricles, and the heart's conduction system. As it proceeds along the coronary sulcus, it gives rise to the right marginal artery, which serves the superficial parts of the right ventricle. Further along, on the heart's posterior surface, the right coronary artery also gives rise to the posterior interventricular artery, or posterior descending artery. This artery travels down the posterior portion of the interventricular sulcus towards the heart's apex, delivering blood to the interventricular septum and portions of both ventricles.
