WORK ACCOMPLISHED BY HEMODYNAMICS RESEARCH, (1964-1965)

Abstract

Using a pressure gun and cartridges of liquid silicone, the aortal systems of freshly-killed calves were injected under physiological pressures. The injected material attained a permanent set within minutes, allowing dissection and removal of the entire system. Artery walls were removed by corrosion. The resultant casts -- the first precise geometric models of the animal aortal system -- showed a number of heretofore unpublished characteristics, i.e., the orifices of segmentally distributed arteries are elliptical in shape with rostral, gradually deepening troughs. The aorta itself shows a characteristic distrotion at the junction of the previously existent ductus arteriosus. The influence of these peculiarities upon blood flow within the system is at present being investigated.
