Circulation question

    I did an Altius FL and I found a question about circulation that confused me. The answer is anchored on the fact that arteries do not have the ability to dilate. I have always thought that they did dilate. Have I been wrong all this while or is this information wrong?

    Thanks!!

      Mind posting the question?

      Smooth muscle allows for the diameter of arteries to constrict and dilate.

        I do understand the explanation and I know that it is most unlikely for arteries to dilate in order for macrophages to get to an injury site. However, I want to make sure I am not missing a fact about dilation and constriction of arteries since the explanation says "Arteries do not have the ability to dilate." Is this just an error in explanation, or am I missing something?

        Thank you!

          Maybe it is a semantics thing...

          Let's take the aorta for example. My understanding is during systole the aorta dilates as it swells with blood, then constricts/rebounds during diastole to push along the blood.

            Makes sense. At least I know for sure that arteries do dilate like you just explained. I think that the explanation given in that particular question may have been worded wrong or weird. Thank you tho!
