I too have a plasma, look. Please listen. Usually, when a blood vessel gets ruptured and we bleed, our blood begins to form a clot. First, the platelets start sticking to the broken vessel and each other. Thus forming a loose plug. But this plug is not enough to stop bleeding. Hence, The clotting factors take part in a complex chain of chemical reactions and create fibrin strands. These strands criss-cross one another and create a mesh that tightly holds the loose plug together. Makes it strong. Red blood cells and white blood cells also get trapped in the mesh. Thus creating a blood clot that completely stops bleeding.
