Explain how the body reacts when a blood vessel is cut
- Damage to a blood vessel causes platelets to stick together at the site of damage and produce clotting substances/thromboplastin.
- Thromboplastin stimulates conversion of plasma protein inactive prothrombin to active thrombin in presence of calcium ions and vitamin K.
- Thrombin catalyzes conversion of soluble plasma protein fibrinogen to insoluble fibrin that forms a mesh network of threads a cross the wound/damaged part n which red blood cells are trapped to form clot.
