Developmental haemostasis is a term used to describe the natural process of the blood clotting system during growth and development. During this process, the body learns to balance the coagulation and anticoagulation factors to prevent excessive bleeding or clotting in different stages of life. Other terms related to developmental haemostasis include haematological development, haemostatic balance, and coagulation maturation. These synonyms emphasize the importance of understanding the complex mechanisms that regulate blood clotting in various life stages. Such knowledge is crucial for identifying and treating different diseases that affect haemostasis, including coagulation disorders, thrombosis, and haemorrhagic diseases.
