Fluid Dynamics of Circulation: Focus on the Kidney

点击翻译按钮获取中文摘要

In Australia, about 30% of adults have hypertension, a major risk factor for heart disease, accounting for about 40% of all deaths. Problems in renal circulation are likely factors leading to hypertension. A detailed understanding of the renal circulation, of whose hydraulic characteristics we have limited knowledge, is required before we can cure or prevent hypertension. We will determine how the size, structure and geometry of the blood vessels influence the function of the kidney. This will lead to predictive models to aid the design and interpretation of physiological studies and the combat of hypertension. It will also help in the ongoing development of bioartificial kidneys to replace present dialysis systems.
