Hey, everyone. Let's take a look at this question together. The ascending aorta gives rise to which important arteries is it? Answer choice. A, the coronary arteries, answer choice B, the carotid arteries, answer choice. C the renal arteries or answer choice. D the femoral arteries. Let's work this problem out together to try to figure out which of the following arteries come from the ascending aorta. So we can recall from what we have learned about the structure of the heart specifically related to the aorta. We note that the ascending aorta, which is the term that describes that first segment of the aorta arises from the left ventricle. So that means that the ascending aorta gives rise to the artery that come out of the left ventricle. And these arteries are responsible for supplying that oxygenated blood directly to the heart. So looking at our answer choices, which artery best supports the idea that these arteries arise from the left ventricle and supply the oxygenated blood to the heart. And we know that answer choice. A the coronary arteries are the correct arteries. So answer choice. A is the correct answer. Since those coronary arteries are responsible for supplying the oxygenated blood to the heart and they also arise from the left ventricle. So answer choice A is the correct answer and answer choices. BC and D are all incorrect since they do not arise from the ascending aorta. I hope you found this video to be helpful. Thank you and goodbye.
