    vascular platelet phase, activation of the coagulation cascade and the activation of a control mechanism. Mostly, the system is triggered by a damaged blood vessel. After vascular injury, rapid vasoconstriction will serve to reduce blood flow. At the same time, von Willebrand factor (vWf) will act as a bridge between endothelial collagen and platelet surface receptor glycoprotein Ib (GPIb) which will promote platelet adhesion (Green, 2006). After platelet adhesion, degranulation from the platelet granules

    have a normal number of platelets in the blood. Blood is made up of three major cell types: red blood cells, which carry oxygen throughout the body; white blood cells, which help fight infection; and, platelets, which stick together at the site of a cut or wound to form a clot to stop the bleeding. People who have thrombocytopenia don’t have enough platelets to form a blood clot, and so they may bleed excessively when they are cut. (nhlbi.nih.gov, 2013) Blood cells and platelets are made in the bone

    Platelet-activating factor (PAF) or phospholipid, 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine is a phospholipid activator and mediator of leukocyte functions that has many physiological actions. It was discovered and many studies have been done to characterize its messenger functions as a phospholipid.1 PAF is produced by many different cell types such as leukocytes, platelets, mast cells and vascular endothelial cells. PAF amplifies inflammatory responses by promoting leukocyte activation and

  • Bernard Soulier Syndrome Essay

    1012 Words  | 5 Pages

    Bernard-Soulier syndrome is an inherited platelet disorder caused by a defect in a gene responsible for a receptor that aids platelets in adhering to the lining of injured blood vessels. This disorder is characterized by thrombocytopenia and large nonfunctional platelets (Pham,2007). Patients often present initially with bleeding symptoms such as purpua, epistaxis, ecchymosis, bleeding of the gums, and menorrhagia (Lanza,2006). Diagnosis is further confirmed by platelet aggregation studies and flow cytometry

  • Essay On Haemostasis

    1705 Words  | 7 Pages

    Haemostasis is a physiological process of blood clotting and dissolution of the clot, followed by the repair of injured tissue. It results from interplay of vascular endothelium, platelets, coagulation factors, anti-coagulation mechanisms and fibrinolytic system. The fluidity of blood in the absence of injury is maintained by the balance between pro-coagulant pathway, and the mechanisms that inhibit the pro-coagulant pathway. Imbalance between the two mechanisms, for example during clinical illnesses

    What is thrombocytemia and thrombocytosis? The word breakdown of each word is as follows thrombocytemia - thromb/o - platelet, cyt/o - cell, suffix -emia - condition of the blood; and thrombocytosis - thromb/o- platelet, cyt/o - cell, suffix -osis - abnormal condition. Both mean that there is an abnormal amount of platelets in the blood. Platelets assist in the clotting process. How is thrombocytemia diagnosed?

    Disseminated Intravascular Coagulation (DIC) Disseminated intravascular coagulation (DIC) is a case of uncontrolled activation of proteins that are involved in the clotting process such as thrombin, fibrinolytic proteins, platelets, and coagulation factors. DIC occurs due to inflammation, trauma, infection, and shock. The presence of mucocutaneous bleeding is an evidence of DIC. Disseminated intravascular coagulation has acute and chronic phases. In acute phase, a patient will have severe symptoms

    bone marrow to create too many red blood cells, white blood cells, or platelets.” Normally, the bone marrow would make immature blood cells, or blood stem cells, that would develop into a myeloid or lymphoid stem cell. The lymphoid cell would develop into a white blood cell, and the myeloid cell would develop into either a red blood cell, platelet, or a white blood cell. The white blood cells fight disease and infection, the platelets clot the blood, and the red blood cells carry oxygen throughout the

  • Essay On Thrombosis

    1464 Words  | 6 Pages

    Thrombosis Formation Thrombosis is the formation of a thrombus within the vascular system. Development of thrombosis after vessel wall injury is characterised by the deposition of platelets, tissue factor and fibrin. A thrombus is a solid or semi-solid mass, which consists of aggregated platelets, that form a platelet plug and a mesh of cross-linked fibrin protein. The formation of a thrombus is a healthy response to blood vessel injury intended to prevent blood loss, and is the first step in restoring

  • Essay On Prosthetic Heart Valve

    711 Words  | 3 Pages

    Bioprosthetic valves used in heart valve replacement generally offer functional properties that are more similar to those of native valves. Implantation of prosthetic cardiac valves to treat hemodynamically significant aortic or mitral valve disease has become increasingly common. Replacement of diseased valves with prosthetic heart valves reduces the morbidity and mortality associated with native valvular disease, but it comes at the expense of risking complications related to the implanted prosthetic

  • Essay On Blood Clots

    1031 Words  | 5 Pages

    THROMBOSIS When a blood vessel is injured, the cells of your blood bond together to form a blood clot. The blood clot helps you stop bleeding. Blood clots are made of a combination of blood cells, platelets (small sticky cells that speed up the clot-making process), and fibrin (protein that forms a thread-like mesh to trap cells). Doctors call this kind of blood clot a “thrombus.” Blood clots are good when they help seal a cut to stop bleeding. But sometimes, a blood clot can form when it is not

  • Essay On Thrombocytosis

    776 Words  | 4 Pages

    Introduction Thrombocytosis is when you have too many platelets (thrombocytes) in your blood. Platelets are parts of blood that stick together and form a clot (thrombus) to help your body stop bleeding. Some conditions that cause inflammation, such as cancer, may trigger your body to make more platelets than normal. There are two types of thrombocytosis. Primary or essential thrombocytosis happens when abnormal cells in the bone marrow make too many platelets. Reactive thrombocytosis happens when a condition
