The tunica media is thicker in the arteries rather than the veins. The outer layer is the tunica adventitia and the thickest layer in veins. It is ...

  9. Coronary circulation - Wikipedia

    en.wikipedia.org/wiki/Coronary_circulation

    Cast of coronary arteries (right = yellow, left = red) There are some anastomoses between branches of the two coronary arteries. However the coronary arteries are functionally end arteries and so these meetings are referred to as potential anastomoses, which lack function, as opposed to true anastomoses like that in the palm of the hand. This ...
