Intravascular blood coagulation is prevented by the presence of___________?
Show answer Hide answer
Answer: C. Heparin
Explanation
Heparin acts directly within the circulatory system to prevent dangerous blood clots. Anticoagulant agents inhibit specific clotting factors to maintain normal blood fluidity. Natural biochemical inhibitors prevent excessive intravascular thrombosis during circulation. Hemostasis involves a complex cascade of clotting factors and platelets. Anticoagulants counteract the clotting cascade to keep flowing blood liquid. Medical professionals administer pharmaceutical grade heparin during surgical procedures.
Hospitals use heparin to prevent clotting during delicate cardiovascular surgeries. Patients with certain heart conditions receive anticoagulants to lower stroke risks. Understanding clotting mechanisms helps researchers develop better thrombosis therapies. Haemoglobin serves as the primary oxygen carrying protein within red blood cells. Fibrin actually forms the structural mesh that promotes blood clot formation. Plasma is the fluid component suspending blood cells rather than an anticoagulant.
