摘要：
Processes of unsteady transcapillary exchange in hemodynamics with allowance for plasma motion in the interstitial space are studied by methods of physical and mathematical modeling. The presence of pulse oscillations of pressure in the network of capillaries is responsible for separation of filtration and re-absorption through capillary walls in space and time. General and specific properties of functioning of the arteriole, intermediate, and venule segments of the capillary network in exchange properties are demonstrated. Pressure oscillations are found to enhance transcapillary exchange.
