Haemostasis-blood must be maintained in a fluid state in order to function as a transport system, but must be able to solidify to form a clot following vascular injury in order to prevent excessive bleeding, a process known as haemostasis. It is localised to the tissue damage and is followed by removal of the clot and tissue damage..
