In hematology, thrombocythemia is a condition of high platelet (thrombocyte) count in the blood. Normal count is in the range of 150 × 10 9 to 450 × 10 9 platelets per liter of blood, [1] but investigation is typically only considered if the upper limit exceeds 750 × 10 9 /L. When the cause is unknown, the term thrombocythemia is used, as ...
In hematology, essential thrombocythemia (ET) is a rare chronic blood cancer (myeloproliferative neoplasm) characterised by the overproduction of platelets (thrombocytes) by megakaryocytes in the bone marrow. [ 3 ] It may, albeit rarely, develop into acute myeloid leukemia or myelofibrosis. [ 3 ] It is one of the blood cancers wherein the bone ...
Blood coagulation pathways in vivoshowing the central role played by thrombin. Health. Beneficial. Coagulation, also known as clotting, is the process by which bloodchanges from a liquidto a gel, forming a blood clot. It results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair.
Dependent on location. 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. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to ...
Platelets or thrombocytes (from Ancient Greek θρόμβος (thrómbos) 'clot' and κύτος (kútos) 'cell') are a blood component whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot. [ 1 ] Platelets have no cell nucleus; they are fragments of ...
Immune thrombocytopenic purpura (ITP), also known as idiopathic thrombocytopenic purpura or immune thrombocytopenia, is an autoimmune primary disorder of hemostasis characterized by a low platelet count in the absence of other causes. [1][2] ITP often results in an increased risk of bleeding from mucosal surfaces (such as the nose or gums) or ...
Endocytosis: The membrane of the cell invaginates, creating a small circular pit that is taken into the cytosol of the cell. This circular membrane coated pit is a vesicle that is transported to the lysosome of the cell to be degraded by enzymes. -Cytosis is a suffix that either refers to certain aspects of cells ie cellular process or ...
In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. Hemostasis involves three major steps: vasoconstriction; temporary blockage of a hole in a damaged blood vessel by a platelet plug
