Caption: Light micrograph of female human blood cells, showing numerous red cells (erythrocytes) and three neutrophils (white cells). The pink-staining erythrocytes are biconcave discs of haemoglobin that carry oxygen and carbon dioxide to & from tissues. Neutrophils function by engulfing invading microorganisms, particularly bacteria. The neutophil's most prominent feature is its multi-lobed nucleus (purple stain). In neutrophils of females, the condensed X-chromosome (Barr body) exists as a small, drumstick-shaped appendage of one of the nuclear lobes. A drumstick chromosome is visible in the neutrophil at far right. Magnification: x400 at 35mm size.
