Resistance in the Venous system is very small and is thus able to return blood to the heart with ease. Capillary Exchange – transfer of liquid and solutes between blood and interstitial fluid; such as Oxygen, CO2, waste. Pressure: BP= blood pressure, CHP = capillary hydrostatic pressure – P in capillary beds (35-18 mmHg), Venous pressure – P in venous system; very low, venule to right atrium is 18 mmHg **∆P across entire systemic circuit = ‘Circulatory Pressure’ ~ 100mmHg, must overcome total ‘Peripheral…
