[Comparative characteristics of changes in the diameters of microvessels and blood flow within them during systemic shifts in hemodynamics].
In anesthetized cats, with the aid of the method of television line single out, the diameters of mesenteric microvessels and their blood flow were studied. The diameter of the flow in arterioles and venules was shown to undergo greater changes than the diameter of the microvessels proper, although a close correlation was revealed between both parameters. The above differences of the changes of diameters are more obvious during dilatory responses. The changes depend on the initial caliber of the arterioles and venules.
