Question

Quizplus · Accepted Answer

Blood hydrostatic pressure is the most important force driving filtration at the arterial end of a capillary. It is the pressure exerted by the blood on the walls of the capillaries due to the pumping action of the heart. This pressure is higher than the interstitial hydrostatic pressure, tissue fluid colloid osmotic pressure, and blood colloid osmotic pressure, which causes the water and small solutes to move out of the capillaries and into the interstitial space. This filtration process is essential for delivering nutrients and oxygen to the surrounding tissues.
