Clotting of blood, Blood clotting
Now we are going to read what is blood clotting. When there is a scratch somewhere in our body, then blood starts coming out from there and after some time the blood accumulates there, that is called blood clotting. If the blood clot is not formed, then the blood flow of our body does not stop, due to which the person can also die.
How is blood clotting formed
Now we understand how blood clots, which we call the cascading process. The cascading process is completed in 4 steps.
Step 1:- As soon as our thrombocyte is cut, it comes in contact with air, due to which it reacts to form thromboplastin.
Step 2:- In step 2, thromboplastin reacts with calcium and prothrombin inside our body to form thrombin. Thrombin is activated at the same time when our body cares for blood due to scratch and that blood flow has to be stopped.
Step 3:- In step 3, thrombin reacts with fibrinogen inside our body to form fibrin.
Step 4:- In step four, the fibrin makes its plexus-like shape and goes to the place from where the blood flows, due to which the blood cells are not able to pass from there, hence clotting of blood starts there.
