Légende : Grossissement : x 10 000 pour 14 x 9,5 cm. This highly enlarged scanning electron micrograph (SEM) depicted a closer look at the details exhibited by of number of red blood cells found enmeshed in a fibrinous matrix on the luminal surface of an indwelling vascular catheter; Magnified 11397x. In this instance, the indwelling catheter was a tube that was left in place creating a patent portal directly into a blood vessel. 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 stabilizing and strengthening the clot, in much the same way as rebar acts to strengthen and reinforce cement.
