Answer 1

Blood coagulation is the major chemical defense against blood loss.

a. true

• Blood coagulation is an important process for preventing blood loss by excessive bleeding due to injury of blood vessels
• It prevents the bleeding by forming a clot over the injury
• Platelets and protein in the plasma work together to form a ''Fibrin plug'' that is the final clot
• Vitamin K is needed by the body for a blood clot and healing of the wound.
