Now, to see exactly what we mean by that, let's take a look at the following diagram. This diagram describes the cells of some particular tissue and the cells are shown in brown. It also describes the capillary system that is found within our tissue. And wherever we have a capillary system, we also have a Lymph system. And the vessel of the Lymph system is shown in green. So basically, we have the arterial, the blood vessel shown in red, that brings the oxygenated and the nutrient filled blood to the capillary of our blood vessel system.
