And within the capillary, we have exchange between nutrients and wastes taking place. And then the Venuel is the blood vessel that carries the deoxygenated blood that contains the waste products back to the heart. So let's recall how the exchange of nutrients and waste products takes place within our capillary. So, if we examine the arterial side of the capillary, on the arterial side, we have a higher hydrostatic pressure than osmotic pressure. And that's exactly why that hydrostatic pressure is able to force the blood plasma that contains the nutrients and our oxygen from the capillary and into the surrounding tissue space. And the surrounding tissue space is known as the interstitial tissue.
