Vasoconstriction occurs in the: the volume of fluid reabsorbed at the venous end of a capillary is nearly equal to the volume of fluid filtered out at the arterial end.
WebThe results indicated that a change in the pH value of the culture medium affected the cytosolic pH of the endothelial cells, which then led to a change in vascular diameter. When the medium's pH ranged from 7.4 to 7.6, the diameter of the lumen formed in the Matrigel was suitable for capillary formation in tissue engineering.
