Coloured Tem Of Red Blood Cells In An Arteriole
Photograph - Photograph
Red blood cells. Coloured transmission electron micrograph (TEM) of a section through red blood cells in a blood vessel in human skin. The vessel is an arteriole, a small artery. Red blood cells (erythrocytes) are seen stacked together in rouleau" formation due to their convex shape. They are passing through the lumen (pink) of the arteriole. Walls of the arteriole (brown) are made up of a single layer of endothelial and muscle cells. Up to 40% of the blood consists of red blood cells that contain haemoglobin which trans- ports oxygen around the body. Each day a red blood cell travels about 15km through the body's blood vessels.
