Coagulation Pathways
Coagulation pathways are processes in the body that help control bleeding when injuries occur. They involve a series of chemical reactions, where proteins in the blood, called clotting factors, work together. There are two main pathways: the intrinsic pathway (activated by damage to blood vessels) and the extrinsic pathway (triggered by tissue injury). Both pathways converge into a common pathway that forms a stable blood clot, allowing the wound to heal. Essentially, these pathways ensure that bleeding stops effectively, preventing excessive blood loss and promoting recovery.

Coagulation pathways are the processes by which blood clots form to stop bleeding. When a blood vessel is injured, various proteins in the blood activate in a step-by-step sequence, which can be divided into two main pathways: the intrinsic and extrinsic pathways. The intrinsic pathway responds to damage within the vessel, while the extrinsic pathway reacts to external injury. Both pathways lead to the common pathway, culminating in the transformation of a protein called fibrinogen into fibrin, which forms a mesh that stabilizes the clot. This intricate system ensures that bleeding is controlled efficiently.
