The left ventricle, valve and aorta may have some special interactions to increase efficiency in work. At first, a pulsatile pump and ultrasonic flow meter are used in this research to find out if a resonance occurs and how it influences the flow rate when an elastic tube is tested. Compare the results from three elastic tubes with the result from the non-elastic one. Then, does the integral flow volume also have a significant change around the resonant frequency? The elastic expansion and recoil should be measured to prove the assumption of resonance in latex tube. Finally, we adjust the apparatus to a heart-like mode and show its better performance around the resonant frequency.
