Capillaries. These are the vessels where blood is able to transfer the sugars and oxygen it carries into your tissues. If you have high blood pressure or are an alcoholic, these are what cause your nose to turn red when they burst. They are only one cell wide and are slightly too small for red blood cells. After the RBCs start getting older the trip through the capillary damages them and they eventually get "eaten" by the immune system. RBCs last about 100 days.
