Brain blood vessels. Confocal light micrograph of a transverse section through a brain showing two blood vessels (black). Surrounding the blood vessels are neurons (nerve cells, red) and glial cells (support cells, green). The red blood cells in the blood vessels distribute oxygen to the brain and carry waste carbon dioxide away from it.
