Uses detailed microvascular data for certain animal tissues to specify the components of the network model of the blood microcirculation presented in P-4636. Quantitative morphological information on the rabbit omentum, cat mesentery, cat tenuissimus muscle, bat wing, and rat cremaster muscle was used to calculate the hydraulic resistance and compliance of the microvessels, to determine the decay of pulsatile pressure. Results are presented graphically. In most capillary networks, the pulsatile pressure amplitude is shown to be highly damped before it reaches the mid-capillaries. (Presented at the Seventh International Conference on Microcirculation, Aberdeen, Scotland, August 1972.) 11 pp. Ref.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
