Final answer:
Complete hemostasis arrests the flow of blood. It involves vascular spasm, platelet plug formation, and coagulation, resulting in a stable fibrin clot that stops bleeding from minor injuries.
Step-by-step explanation:
The common body fluid that is arrested by complete hemostasis is blood. Hemostasis is the physiological process that stops bleeding and consists of three steps: vascular spasm, the formation of a platelet plug, and coagulation. Vascular spasm constricts the flow of blood, the platelet plug temporarily seals small openings in the vessel, and coagulation involves the production of a fibrin clot, which is a meshwork that stabilizes the plug and includes trapped platelets and blood cells.
In cases of minor injuries, hemostasis effectively prevents blood loss, but severe damage leading to hemorrhage may require medical intervention to restore blood volume and maintain blood pressure to manage the significant loss of blood.
