Study Notes
Haemostasis
- Haemostasis is the process of stopping bleeding or blood loss from a damaged blood vessel
- It involves three main stages: vasoconstriction, platelet plug formation, and coagulation
- Vasoconstriction is the constriction of blood vessels to reduce blood flow to the damaged area
- Platelet plug formation involves the aggregation of platelets to form a temporary plug to seal the damaged vessel
- Coagulation is the process of forming a blood clot, which is a solidification of blood, to permanently seal the vessel
Learn about the three stages of haemostasis: vasoconstriction, platelet plug formation, and coagulation, which help stop bleeding from damaged blood vessels.
