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. So what happens is when the blood plasma leaves the capillaries and enters this cell tissue area, that brings the nutrients, such as glucose and fats and amino acids and oxygen to the cells of that surrounding tissue. And at the same time as that fluid travels along the tissue space, along the interstitial tissue, it picks up those waste products that are secreted by the cell, such as carbon dioxide and ammonia. And once the fluid is on the Venuel side, on this side of the capillary, because the zmotic pressure is now greater than the hydrostatic pressure, the blood rushes back into the capillary of our body.
