describe blood cloating
Answers
Explanation:
blood clotting is defined as a large amount of blood collected at a place inside our body .
The injured tissue cells and the platelets which disintegrate at the site of the wound releases a substance thrombokinase (also called thromboplastin). The thrombokinase acts as an enzyme and with the help of calcium ion present in the plasma, it converts a substance prothrombin (inactive) of the plasma, into thrombin (active).
Thrombin in the presence of calcium ions, react with the soluble fibrinogen of the plasma to convert it into insoluble Fibrin. It is a solid substance that forms thread. These microscopic threads of fibrin are sticky and form a network (mesh) at the wound.
Blood cells are trapped in the network of the fibrin; the network then shrinks and squeeze out of the rest of the plasma which is in the form of clear liquid, the serum. The solid mass which is left behind is called clot, (or thrombus).
