What is the difference between intrinsic and extrinsic blood clot formation?
Intrinsic blood clot formation occurs due to factors within the blood vessels, such as damage to the vessel wall or abnormal blood flow. Extrinsic blood clot formation, on the other hand, is triggered by external factors outside the blood vessels, such as trauma or surgery. Both intrinsic and extrinsic pathways ultimately lead to the formation of a blood clot, which is a normal response to prevent excessive bleeding.
