How does blood clotting work after a cut?
Human BiologyPhysiology
Quick Answer
When a blood vessel is damaged, platelets gather and clotting proteins form a mesh that seals the wound. This stops bleeding and creates a temporary repair.
The Full Story
Blood clotting begins when damaged tissue exposes signals that activate platelets. Platelets stick to the injury site and release chemicals that recruit more platelets. At the same time, clotting factors in the blood trigger a cascade that converts fibrinogen into fibrin, forming a mesh that stabilizes the platelet plug. This process is tightly regulated so clots form where needed but do not block healthy vessels.
Key Facts
1.Platelets are the first responders in clotting
2.Fibrin forms the mesh that stabilizes a clot
3.Clotting is controlled to prevent unwanted vessel blockage
