An analysis of extramuscular branches of the coronary arteries in relation to size and weight of heart.

There is close relationship between the size and weight of the heart and the angles of branching of coronary arteries. The velocity of flow of liquids through a system of branching ducts may be related to the valued function of angles of branching ducts. We estimated the effect of the phenomenon on blood flow through the extramuscular branches of the coronary arteries. The estimation was based on measurements of angles of division of the arteries in 48 human hearts. It was also correlated with weight and dimensions of the heart.
