Abstract：
:The "Gamma Loop" Part I compared a model of rubber tubing to the architecture of the glomerulus with emphasis placed on the observed relationship between the position of the outflow resistance clamp and the perfusion of the loop (1, 2). Part II describes the pressures observed in the different parts of the loop, as well as the effect of another outflow branch which imitates "filtration".
