Answer: Antibodies are proteins that are found in the body on the surface of red blood cells and in the blood plasma ,they are very sensitive to foreign bodies and bad viruses and bacteria,when they notice the presence of anything that poses harm or a threat to the body system,they track it down and fight/destroy it.
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.
