Final answer:
The international normalized ratio (INR) helps to regulate blood clotting.
Step-by-step explanation:
The international normalized ratio (INR) is a standardized system of reporting the prothrombin time (PT) and helps to regulate blood clotting. The INR measures the speed of a particular pathway of coagulation and compares it to normal. If the INR is increased, it means it is taking longer than usual for blood to clot.
Blood clotting is an important process to prevent excessive bleeding and maintain homeostasis in the body. It involves a series of complex reactions and the activation of various clotting factors. The INR helps to ensure that blood clotting occurs within the appropriate range.
