Blood cells. Artwork (based on a scanning electron micrograph) showing various blood cells escaping from a sectioned small vein (top right). Red blood cells (erythrocytes) appear as biconcave discs; the knobbly red cells have become crenated (this occurs in high plasma concentrations). Red blood cells contain the oxygen-transporting pigment haemoglobin that circulates oxygen around the body. White cells (leucocytes) appear white; some (known as B-lymphocytes) have numerous microvilli projecting from their surfaces. The smaller branched structures (brown) are blood platelets | |
