Caption: Color enhanced scanning electron micrograph (SEM) of red blood cells found enmeshed in a fibrinous matrix on the luminal surface of an indwelling vascular catheter; Magnified 11432x Note the biconcave cytomorphologic shape of each erythrocyte, which increases the surface area of these hemoglobin-filled cells, thereby, promoting a greater degree of gas exchange, which is their primary function in an in vivo setting. In their adult phase, these cells possess no nucleus. What appears to be irregularly-shaped chunks of debris, are actually fibrin clumps, which when inside the living organism, functions as a key component in the process of blood clot formation, acting to entrap the red blood cells in a mesh-like latticework of proteinaceous strands, thereby,
