Delivering blood to the heart itself, the coronary arteries ensure that our vital pumping organ stays well-nourished. 

In this image of a zebrafish heart, we can see developing coronary vessels and their lining endothelial cells in green

Blue marks the developed coronary arteries and migrating endothelial cells. The nuclei of the heart’s muscle cells (cardiomyocytes) in the muscle layer (myocardium) are shown in purple.
