Fractals in Us

The Circulatory System

The heart is filled with fractal networks: the coronary arteries and veins, the fibers binding the valves to the heart wall, the cardiac muscles themselves, and the His-Purkinje system.
In addition to falut-tolerance during growth, fractal branching makes available much more surface area for absorption and transfer in capallaries.
Kalda has proposed a fractal model of the blood vessel system that achieves a homogeneous oxygen supply throughout the body.
A portion of the circulatory and pulmonary systems is seen on the right, in another picture provided by Dr. Ewald R. Weibel. Click the picture for a larger version in a new window.
From his work on the ability of fractal drums to damp vibrations, Bernard Sapoval deduced another advantage of the fractal character of the circulatory system: "the fractal structure of the human circulatory system damps out the hammer blows that our heart generates." "The heart is a very violent pump, and if there were any resonance in blood circulation, you would die."
Fractals may save our lives every minute.
