Description
Blood clot. Colored scanning electron micrograph (SEM) of a human blood clot. Here it has formed inside a blood vessel following an injury. Red blood cells (erythrocytes) are seen trapped by a web of brown fibrin threads. The fibrin is an insoluble protein and these threads are an essential mechanism for the arrest of bleeding. As the blood cells become trapped they lose their normal rounded shape (as at upper left). Blood clots form to repair blood vessels damaged by injury or disease. Abnormal clotting as occurs in a thrombus in intact arteries and veins is the principal cause of heart attack and stroke. Magnification x2500 at 6x6cm size.
