pulsatile networks is essentially identical to how national power grids are designed for the efficient transmission of electricity over long distances. This condition of nonreflectivity is called impedance matching. It has multiple applications not only in the working of your body but across a very broad spectrum of technologies that play an important part in your daily life. For example, telephone network systems use matched impedances to minimize echoes on long-distance lines; most loudspeaker systems and musical instruments contain impedance matching mechanisms;
