WebFigure 5.5.1 summarises the three steps of haemostasis. Figure 5.5.1. Haemostasis. (a) An injury to a blood vessel initiates the process of haemostasis. Blood clotting involves three steps. First, vascular spasm slows the flow of blood. Next, a platelet plug forms to temporarily seal small openings in the vessel. WebPrimary hemostasis (platelet clotting) Primary hemostasis is when your body forms a temporary plug to seal an injury. To accomplish that, platelets that circulate in your blood stick to the damaged tissue and activate. That activation means they can “recruit” more …
