Hemostasis
Hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). The blood could have problems with carrying out thus clotting process because of drugs (vitamin K for example) and certain conditions, like haemophilia or Von Willebrand disease.
It is the first stage of wound healing. This involves coagulation, blood changing from a liquid to a gel. Intact blood vessels are important to moderating blood's tendency to form clots.[1]
The word hemostasis (/ˌhiːmoʊˈsteɪsɪs/,[2][3] sometimes /ˌhiːˈmɒstəsɪs/) uses the combining forms hemo- and -stasis, New Latin from Ancient Greek αἱμο- haimo- (akin to αἷμα haîma), "blood", and στάσις stásis, "stasis", yielding "motionlessness or stopping of blood".
Hemostasis Media
Aggregation of thrombocytes (platelets). Platelet-rich human blood plasma (left vial) is a turbid liquid. Upon addition of ADP, platelets are activated and start to aggregate, forming white flakes (right vial)
