In progressive development of the organisms, the cardio-vascular system perfects, its construction is adequate to the level and character of the animal's metabolism. The hypobranchial arteries, forming in the subbranchial area in fishes, make the immediate source for the branching off the coronary arteries. Comparison of the data concerning the places where the cranial coronary arteries take their origin in amphibia, reptiles, birds and mammalia demonstrates that the evolutional process is directed towards transference of the places of their branching off on the ventral aorta, and then on the nearest distance to the heart. Certain data are obtained on evolution of the blood circulation pathways in the myocardium and, particularly, on presence of blood vessels in the spongy myocardium in Elasmobranchii, Chondrosteoideii, as well as in the alligator. The most important of the myocardial blood vessels at all stages of evolution is their connection with the cardiac chambers. At definite stages of phylogenesis, simultaneously with compactization of the myocardium and formation of veins from the intertrabecular spaces, the subepicardial and intramural veins unite into a single venous system, bringing blood to the cardiac cavity. In birds, mammalia and human being, the coronary vessels have reached a high degree of development, having penetrated by their branches into all layers of the cardiac wall, and thus they exclude the dependence of the myocardial blood supply from the blood that is present in the cardiac cavity.
