Morphometric Analysis of Capillary Nets in Rat Myocardium
The importance of relevant data with respect to capillary geometry cannot be under-estimated in the modelling of oxygen transport to tissue. C. R. Honig stated “knowledge of capillary length and it’s frequency distribution is essential in modelling O2 transport and indicator dilution data” (Honig et al., 1977). To this end, data have been collected for capillary lengths in skeletal muscle (eg. Honig et al., 1977; Skalak and Schmid-Schonbein, 1986; Potter et al., 1988). The situation in cardiac muscle, to date, is certainly more obscure. This is due to the exigency of developing appropriate facilities for viewing surface vessels of a beating heart in situ; or in the development of morphometric techniques that accurately demarcate capillaries from histological sections.
