[Age-related changes in the parameters of the capillary blood flow in rat skeletal muscle: allometric relations and the hypothesis of capillary functional length].
The effect of growth on the capillary i.d. and density, the RBC velocity and tube hematocrit in the rat m. cremaster was studied in vivo. All these parameters decreased with growing as described by allometric equations. The mean capillary diameter and the hematocrit did not change significantly under the same conditions. A hypothetic explanation of the discrepancy between the bulk flow and capillary flow is suggested.
