What Is Lymph?

4. Tissue Fluid
The whole point of blood circulation is so that the body’s cells can be fed with a constant supply of oxygen, nutrients, and everything else it needs to work properly. This is achieved by the blood bathing the bodily tissues, allowing the bloods precious cargo to be delivered. In order to do this, red blood cells and other molecules pass through the walls of the capillaries.
When the blood is bathing the tissues in this way, it is known as tissue fluid. Here, the tissues absorb what they need, while the tissue fluid also collects waste products from the cells. The tissue will then flow into the lymphatic system, where these waste products and any pathogens can be dealt with.
