Antibodies also play crucial role in hemostasis(stoppage of bleeding) in the sense that when the body is wounded or when someone gets a cut antibodies that are found in the plasma and some substances found in the platelets are released to play a role in sending signal to the blood clotting factors in the blood to be released to arrest the bleeding and prevent the person from bleeding out their entire blood.
