Thrombosis (from Ancient Greek θρόμβωσις (thrómbōsis) 'clotting') is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system.
Platelet storage pool deficiency is a family of clotting disorders characterized by deficient granules in platelets.Individuals with these disorders have too few or abnormally functioning alpha granules, delta granules, or both alpha and delta granules and are therefore unable to form effective clots, which leads to prolonged bleeding.
Glanzmann's thrombasthenia is an abnormality of the platelets. [2] It is an extremely rare coagulopathy (bleeding disorder due to a blood abnormality), in which the platelets contain defective or low levels of glycoprotein IIb/IIIa (GpIIb/IIIa), which is a receptor for fibrinogen.
The term thrombocyte (clot cell) came into use in the early 1900s and is sometimes used as a synonym for platelet; but not generally in the scientific literature, except as a root word for other terms related to platelets (e.g. thrombocytopenia meaning low platelets).
Giant platelet disorders, also known as macrothrombocytopenia, are rare disorders featuring abnormally large platelets, thrombocytopenia and a tendency to bleeding. Giant platelets cannot stick adequately to injured blood vessel walls, resulting in abnormal bleeding when injured.
Thromboxane A 2 (TXA 2) is a type of thromboxane that is produced by activated platelets during hemostasis and has prothrombotic properties: it stimulates activation of new platelets as well as increases platelet aggregation.
Air traps or stand pipes (open at the top) are sometimes added as dampers to water systems to absorb the potentially damaging forces caused by the moving water. For example, the water traveling along a tunnel or pipeline to a turbine in a hydroelectric generating station may be slowed suddenly if a valve in the path is closed too quickly.
