Mann, in Hematology (Seventh Edition), 2018. Because this is a multi-step process, separate in vitro tests are often carried out for inhibition of platelet aggregation by collagen, ADP, arachidonic acid, or other substrates. Within the marrow the abundant granular cytoplasm of the megakaryocyte divides into many small segments that break off and are released as platelets into the circulating blood.

Red blood cells are responsible for carrying oxygen and Thrombocytes (platelets) play an important role in hemostasis, by plugging and repairing damaged blood vessels, thus preventing blood loss. People with high platelet levels often don't have signs or symptoms. The concentrations of physiologically important ions of the plasma, notably sodium, potassium, and chloride, are precisely controlled by their retention or selective removal as blood flows through the kidneys.

If platelets are absent, this important defense reaction cannot occur, and protracted bleeding from small wounds (prolonged bleeding time) results. Various granules can contain: PF4 (platelet factor 4), vWF(von Willebrand Factor), and platelet derived growth factor, fibrinogen, fibronectin, vitronectin and thrombospondin, Dense granules ( granules) are electron-dense and contain small molecules such as ADP, serotonin and calcium. Megakaryocytes mature in the bone marrow, and platelets are released into the circulation when megakaryocytes undergo fragmentation that results in the release of over 1,000 platelets per megakaryocyte. The normal resistance of capillary membranes to leakage of red cells is dependent upon platelets. The fact that platelets express inflammatory mediators, which appear to be mostly dispensable for their hemostatic functions, supports the idea that they might contribute to inflammatory conditions, such as rheumatic diseases. 
Examples include: Less commonly, very high platelet levels may cause bleeding. When the blood vessels carrying blood are damaged, the blood coagulates to form thickened masses of blood tissue called clots, which plug the damaged vessel and prevent excessive bleeding.
