What do thrombocytes do?

• A. They help to rid the body of foreign material.
• B. They are involved in antibody formation.
• C. They carry oxygen to cells.
• D. They are involved in blood clotting

Answer: (D)

Thrombocytes, or platelets, are essential for stopping bleeding. When a blood vessel is injured, platelets quickly stick to the exposed area, become activated, and release substances that recruit more platelets to form a cluster. This platelet plug provides a rapid, initial barrier to blood loss. They also support the coagulation cascade, helping convert fibrinogen to fibrin to stabilize and solidify the clot. This combination of forming a plug and reinforcing it with fibrin is what truly curbs bleeding and seals the wound. The other options describe functions of different cell types: removing foreign material is done by phagocytes, antibody formation by B cells/plasma cells, and carrying oxygen by red blood cells.
