Transcapillary Exchange in Relation to Capillary Circulation
Transcapillary exchange of diffusible solutes depends on capillary blood flow, Q; capillary permeability, P; and capillary surface area, S. In a single capillary, the extent of equilibration of a given solute depends on the ratio of Q, to the product of P and S. In a microvascular bed consisting of many capillaries, equilibration depends on the fraction of them which are open to blood flow at a...
متن کاملCardiac microcirculatory effects of beta-adrenergic blockade during sympathetic stimulation.
The effects of beta-adrenergic blockade on cardiac transcapillary exchange were examined at rest and during sympathetic stimulation. Multiple indicator dilution experiments were carried out in closed-chest anesthetized dogs at rest and during carotid occlusion, either under basal conditions or after beta-adrenergic blockade with alprenolol. beta-Adrenergic blockade at rest had no effect on coro...

The effects of /3-adrenergic blockade on cardiac transcapillary exchange were examined at rest and during sympathetic stimulation. Multiple indicator dilution experiments were carried out in closed-chest anesthetized dogs at rest and during carotid occlusion, either under basal conditions or after fJ-adrenergic blockade with alprenolol. jB-Adrenergic blockade at rest had no effect on coronary f...
متن کاملPhysiologic upper limits of pore size of different blood capillary types and another perspective on the dual pore theory of microvascular permeability
BACKGROUND Much of our current understanding of microvascular permeability is based on the findings of classic experimental studies of blood capillary permeability to various-sized lipid-insoluble endogenous and non-endogenous macromolecules. According to the classic small pore theory of microvascular permeability, which was formulated on the basis of the findings of studies on the transcapilla...
متن کاملA model for capillary exchange1
JOHNSON,JOHN A., AND THEODORE A. WILSON. A model for capillary exchange. Am. J. Physiol. 2 IO(~) : qg-1303. Ig66.A mathematical model based on previous experimental work for material exchange across capillary walls is developed for the case where both capillary flow and transcapillary exchange are taken into account. Solutions are given for very early times and for later times for which an asym...
