Fluid Dynamics Study of Aorta Flow

摘要

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 The resultant casts — the first precise geometric models of the animal aortal system — showed a number of heretofore unpublished characteristics, i.e., the orifices of segmentally distributed arteries are elliptical in shape with rostra, gradually deepening troughs. The aorta itself shows a characteristic distortion at the junction of the previously existent ducts arteriosus. The influence of these peculiarities upon blood flow within the system is at present being investigated.
