Final answer:
Normally, anticoagulants are more abundant than coagulants, which helps to maintain the fluidity of the blood and prevent clotting in the absence of injury.
Step-by-step explanation:
Normally, without the presence of an injury, anticoagulants are more abundant than coagulants; therefore, the blood does not clot. This condition is crucial for maintaining blood fluidity under normal circumstances. Anticoagulants, such as protein C, TFPI (tissue factor pathway inhibitor), and antithrombin, play a key role in limiting coagulation to regions where injury has occurred. These substances counteract the clotting factors to prevent the formation of unwanted blood clots within the vascular system. Coagulation is the process wherein blood forms clots and it includes the activation of platelets and the conversion of fibrinogen into fibrin. However, in a healthy individual without any vascular injury, anticoagulants ensure the blood remains in a liquid state, thus facilitating the regular flow of blood through the circulatory system.
