WebA thrombus (plural thrombi), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis.There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein. The substance making up a thrombus is sometimes called cruor.A thrombus is a healthy … WebThis, in turn, causes the connected fibrin blood clot to retract and condense as well. Consequently, clot retraction decreases the size of the cut or gash by drawing the damaged ends of the blood vessel toward one another. Fibroblasts and epithelial cells proliferate in and around the clot. This serves to help repair the damaged vessel. probability fundamental counting principle https://cathleennaughtonassoc.com
