So as your blood pumps around your body, some of the plasma seeps out of your capillaries and into the surrounding cell structure, washing away any cellular garbage like dead cells and dis-RNA’d proteins left over from the war on drugs diseases. This flows into the lymphatic system and is transported away to filtering and cleaning stations called lymph nodes and the waste eventually finds its way into the kidneys or intestines to be expelled along with the rest of the body’s waste.
