And this is when the waste products, for example, ammonia and Carbon dioxide, will flow into the blood plasma. And then they will ultimately travel to the kidneys and other organs of our body that are responsible for excreting those different types of wasteful. Byproducts now, because we have a difference in pressure, because the pressure that pushes into the tissue on the arterial side is greater than the pressure that pushes inward into the capillary, we see that there's going to be a net loss of fluid to the tissues. In fact, there is a net loss of about 10% of the fluid that exists that takes place and that extra fluid, the 10% of the fluid that leaves our capillaries into our Lymphatic system. And the Lymphatic system ultimately returns that fluid to our blood circulating throughout our circulation system. And we'll talk much more about what the Lymphatic system is in a future lecture.
