Network analysis of microcirculation of cat mesentery.
TLDR
Computed and in vivo intravascular pressures show a marked disparity on the arterial side of the true capillaries and a fair agreement on the venous side, attributed to the effects of precapillary sphincter action and non-Newtonian rheological behavior.About:

Adaptive regulation of wall shear stress to flow change in the canine carotid artery
Akira Kamiya,Tatsuo Togawa +1 more
TL;DR: To study the adaptive response of the vascular wall to blood flow changes, an arteriovenous shunt was constructed between the common carotid artery and the external jugular vein in 12 dogs and showed that r increased with increased flow load and vice versa.

Responses of cerebral arteries and arterioles to acute hypotension and hypertension
Hermes A. Kontos,E. P. Wei,Rudolph M. Navari,Joseph E. Levasseur,William I. Rosenblum,Jr Jl Patterson +5 more
TL;DR: The responses of cerebral precapillary vessels to changes in arterial blood pressure were studied in anesthetized cats equipped with cranial windows for the direct observation of the pial microcirculation of the parietal cortex and found to be size dependent.

Shear stress regulation of artery lumen diameter in experimental atherogenesis
TL;DR: The adaptive response of the arterial wall and intimal thickening under conditions of increased flow in an atherogenic model was studied in six cynomolgus monkeys fed a diet containing 2% cholesterol and 25% peanut oil.
Journal ArticleDOI
Blood flow in microvascular networks. Experiments and simulation.
TL;DR: The low capillary hematocrits found in mesenteric microcirculatory networks as well as their heterogeneity can be explained on the basis of the Fahraeus effect and phase-separation phenomena.
Journal ArticleDOI
Biophysical aspects of blood flow in the microvasculature
TL;DR: The current understanding of the biophysical processes governing blood flow in the microvasculature is reviewed, and some directions for future research are indicated.

Pulsatile pressures in the microcirculation of frog's mesentery.
TL;DR: Pressure within the microvascular bed of the frog mesentery has been recorded continuously with micropressure transducers and the waveform of the pressure pulses in arterioles and metarterioles closely resembles that in the larger arteries.

Dimensions of Blood Vessels from Distributing Artery to Collecting Vein
TL;DR: Calculations to determine the per cent of total volume in each portion of the vascular bed showed that the venous system accounts for as much as 80% of the total vascular volume.

A repeating modular organization of the microcirculation of cat mesentery.
TL;DR: Since all components of the microbed are enclosed by the boundary vessels the module represents a repeating structure of a nutritional microcirculation which may assist development of structural-functional correlations.
