Artery, trichrome stain

In this trichrome stained specimen of an artery, collagen is colored blue and smooth muscle is red.  Red blood cells (RBCs) in the arterial lumen are brighter red.  The red texture in the upper-left corner of the image is cross-sectioned smooth muscle in the wall of an (unidentified) organ from which this specimen was taken.
