Which components help blood form clots around a tissue injury?

• A. White blood cells and antibodies
• B. Proteins and platelets
• C. Red blood cells and plasma
• D. Water and minerals

Answer: (B)

Blood clotting (hemostasis) relies on platelets and clotting proteins. When a blood vessel is injured, platelets quickly gather at the site to form a temporary plug. At the same time, clotting proteins in plasma trigger a cascade that converts fibrinogen into fibrin, creating a stable mesh that seals the injury. The combination of platelets plus these clotting proteins best explains how a clot forms. Immune components like white blood cells and antibodies aren’t primarily about clot formation, red blood cells and plasma cover general blood components but don’t specifically drive the clotting process, and water with minerals are basic substances, not the biological players that form clots.
