wht was the blood clottin thing exactly


in blood plasma,there is soluble protein called fibrinogen. the chemical releases from platelets and the damage tissue set off a chain, causes fibrinogen changes into fibrin.
fibrin is insoluble. it forms fibers. these fibres form a mesh across the wound. red blood cells and platelets will trap in tangle of fibrin fibres, forming blood clot.
