Injury causes damaged tissue cells to produce prothrombin activator. This, along with a clotting factor produced by the sticky platelets (cell fragments) at the damaged site, cause prothrombin + calcium to make thrombin (blood protein). All the while fibrinogen is stimulated to make fibrin (blood protein). The fibrin ensnares RBCs to form the clot with the platelets.
All factors have to be there for the clotting to occur. Lack of any of them causes bleeding disorders.
Blood Plasma minus clotting factors is called the 'Serum'.
Cyrum
A fragment of a blood cell called a megokaryocte, is responsible for blood clotting. This fragment is called a platelet.
blood serum is blood plasma without the fibrinogen or blood clotting factors
The chief plasma component to the clotting of blood is the platelet. The additional components include blood clotting factors.
Coagulation begins almost instantly after an injury to the blood vessel has damaged the endothelium (lining of the vessel). Exposure of the blood to proteins such as tissue factor initiates changes to blood platelets and the plasma protein fibrinogen, a clotting factor. Platelets immediately form a plug at the site of injury; this is called primary hemostasis. Secondary hemostasis occurs simultaneously: Proteins in the blood plasma, called coagulation factors or clotting factors, respond in a complex cascade to form fibrin strands, which strengthen the platelet plug
Hemophilia is a serious disease because you don't have the right proteins to clot up your blood( called clotting factors) If you cut yourself and you have hemophilia you could bleed to death if you don;t go to the doctor right away.
Platelets, or thrombocytes, are the smallest formed element in the blood. Made of cell fragments, platelets are part of the blood clotting process. Non-formed clotting factors also are critical to blood clotting.thrombocytes
A formed element present in the blood called platelets are essential in blood clotting. Also, chemicals known as clotting factors circulate and are activated by an injury.
no
Thrombocytes are platelets, derived from fragmentation of megakaryocytes. They are not white blood cells.
It is called a fragment, I am not sure though, that's what my teacher told me.
