why blood is not clotting inside the blood vessel?

Question

blood contain some chemical compositions like Heparin.B'coz of this only blood will not get clot but how can this biochemical component will process

Answer 1

Platelets: noncellular structures that function in blood clotting.
Blood Clotting: Platelets break upon hitting the rough area of a wound. It releases a chemical called THROMBOPLASTIN which changes prothrombin (floating in the blood) to THROMBIN. Thrombin now will react with several other chemicals and eventually cause FIBRINOGEN (found floating in the blood). into an insoluble material called FIBRIN.

Answer 2

with a view to clot tissue clotting factors ought to be 'blended up' with the blood. The tissue clotting factors are released from the cells surrounding the blood vessel and can then variety clots via changing fibronigen to 'threads' which then variety the the clot. usually the clotting factors proceed to be outdoors of the blood vessel, which permits the blood to no longer clot on an identical time as in it.

Answer 3

Blood does not NORMALLY clot inside our blood vessels, for which we can be very thankful. When it does, it causes heart attacks, strokes or pulmonary embolism, any one of which can kill. The clotting process is very complex & usually requires the breaking of a vessel, which then causes platelets to clump together & form the foundation of a clot. In this case, a clot is, quite literally, a life-saver. So, blood clots are usually a good thing.

Answer 4

blood is not kept from clotting by heparin unless you are under medication.In order to clod the protein fibrinogen in the plasma need to form proteinstrands of fibrin. This is a process in many steps some of the key factors are contained in the bloodplates, in the case of an injury the plates rupture and release their content
