When a small blood vessel develops a tiny leak, platelets respond within seconds. These small cell fragments constantly circulate and scan vessel walls for signs of damage. When they encounter an injured spot, they instantly stick to the exposed surface. This contact activates them, causing them to change shape and become sticky. Activated platelets release chemical signals that call in more platelets from the bloodstream. As additional platelets arrive, they clump together and form a temporary

When a blood vessel is injured, the body quickly activates platelets. They stick to the damaged area and form a temporary plug. Then clotting proteins (like fibrin) create a mesh that traps blood cells, forming a stable clot. This stops bleeding and allows healing to begin. #BloodClotting #Hemostasis #HumanBiology #BodyDefense #ScienceFacts | Scoolam Foundation

Steps Involved in the Coagulation Cascade 1. Vascular Injury: Blood vessel damage triggers the cascade. 2. Platelet Plug Formation: Platelets adhere to the injury site, forming a temporary plug. 3. Activation of Clotting Factors: - Intrinsic Pathway: Activated by trauma inside the vascular system (slow, complex). - Extrinsic Pathway: Triggered by external trauma (fast, simpler). 4. Common Pathway: Both pathways converge, activating Factor X. 5. Thrombin Formation: Factor X converts prothrombin i
