In fact, about 10% of that fluid that left the capillary and entered our tissue will remain in that interstitial space, in the space surrounding our capillary. The question is, what happens to this 10% fluid if this 10% fluid is not removed in any way, there will be a build up of pressure as a result of the build up of fluid inside that tissue. And that will lead to swelling, the process of edema. And that can lead to very serious medical conditions and medical complications. So to prevent this from happening, what our body does, and specifically what the lymphatic system does, is it drains and removes that fluid into the system of vessels we call lymph vessels or lymphatic vessels. These lymph vessels essentially connect with larger lymph vessels known as lymphanes.
