Are also called thrombocytes, platelets are actually cell fragments of bone marrow cells called megakaryocytes. Platelets are used to form blood clots to control hemostasis.
The process of controlling/stopping bleeding from a broken vessel; platelets are the main component of hemostasis by working with the plasma protein fibrinogen to form a blood clot.
An enzyme in the blood that plays a critical role in hemostasis by converting the plasma protein fibrinogen into fibrin; fibrin secures platelets as they plug a damaged vessel (platelet plug) and the end result is a clot.
The formation of a blood clot within a vessel which obstructs blood flow through the vessel.
A circulating mass in the blood, examples: fatty embolus or an air embolus.
When blood flow is obstructed to an area of the brain causing brain tissue to become ischemic; if blood flow is not immediately restored brain damage will ensue.
A group of hereditary disorders that prevent clots from being formed.
