Blood clot, light micrograph 照片檔

Blood clot. Light micrograph of a section through an arterial thrombus. Blood clots can form in an intact vessel that contains fatty deposits or one that is inflamed. These clots, known as thrombi, cause pain and may damage the tissues served by the vessel. They can be fatal in some cases. Anticoagulants such as warfarin and heparin help inhibit the further growth of the thrombi and prevent new clots from forming. Magnification: x100 when printed at 10 centimetres wide.
