Which arteries are characterized by higher diastolic flow after meals?

The superior mesenteric artery is the correct answer because it is primarily responsible for supplying blood to the intestines, which have significantly increased metabolic demands following a meal. After eating, the digestive process requires increased blood flow to the gastrointestinal tract to facilitate nutrient absorption. As a result, the diastolic flow within the superior mesenteric artery tends to increase after meals. This increased blood flow is essential in meeting the heightened perfusion needs of the intestinal tissues as they engage in digestion and absorption.

In contrast, other arteries listed do not exhibit the same pattern of increased diastolic flow after meals. The internal carotid arteries primarily supply the brain and do not have a direct link to postprandial changes. The renal arteries serve the kidneys, which play a role in filtering blood and fluid balance rather than nutrient absorption. Femoral arteries supply the lower limbs and are not directly affected by digestive processes. Thus, the superior mesenteric artery stands out as the most affected by meal consumption, demonstrating a characteristic increase in diastolic flow following eating.
