Blood coagulation, also known as haemostasis, is a vital physiological process that ensures that blood loss is stopped after injury while maintaining the integrity of the circulatory system. The process of blood clotting is extremely complex and involves a variety of factors that work together to enable a coordinated response to vascular injury. It is important to note that balanced coagulation is crucial. Too strong a clotting response can lead to thrombosis, while insufficient clotting can lead to excessive blood loss. The balance is maintained by various regulatory mechanisms to ensure that coagulation is only activated when necessary.
