The part of a blood cell that helps prevent bleeding by causing blood clots to form at the site of an injury
cells found in the blood that are needed to control bleeding; often used in the treatment of leukemia and other forms of cancer
small disk or platelike structures which function in the clotting of blood by aggregating together and sealing small breaks in blood vessel walls
Cells in the blood which serve to plug holes in the blood vessel walls and assist in forming a clot A detailed description of clotting is available on the general clotting information web pages
Colorless cells whose main function is to control bleeding Platelets are essential to normal blood clotting They can be wiped out during treatment for cancer, leukemia, aplastic anemia and other diseases
Cells that are produced in the bone marrow; platelets control bleeding by causing the blood to clot The liver produces the clotting factors involved in this process If the liver is damaged, then clotting will also be impaired
A cellular component of blood necessary for coagulation The smallest of the cells in the body; they are disk-shaped and are essential for the clotting of blood (More Information )
Tiny blood cells that stick together to stop the flow of blood around a wound to a blood vessel
Granule-containing cellular fragments critical for blood clotting and sealing off wounds Platelets also contribute to the immune response
A blood cell with sticky or adhesive qualities that helps the blood to clot Platelets can attach to plaques that form on artery walls, which can help start or worsen plaque buildup
cells found in the blood that are needed to help the blood to clot in order to control bleeding; often used in the treatment of leukemia and other forms of cancer
A little plate or plaque; specifically a blood platelet, an irregular shaped disk containing granules in the central part and peripherally; protoplasm but no definite nucleus
The smallest of the circulating blood cells The chief function of platelets is to form plugs on damaged areas of the lining of the blood vessels and to initiate blood clots
Platelets are a kind of blood cell. If you cut yourself and you are bleeding, platelets help to stop the bleeding. one of the very small flat round cells in your blood that help it become solid when you bleed, so that you stop bleeding. or thrombocyte Small, colourless, irregular blood cell crucial in coagulation. Produced in bone marrow and stored in the spleen, platelets accumulate to block a cut in a blood vessel and provide a surface for fibrin strands to adhere to, contract to pull the strands together, and take part in the conversion sequence of coagulation factors. They also store and transport several chemicals
general shape of a montmorillonite particle, consisting of a sheet-like structure where the dimensions in two directions far exceed the particle’s thickness
A small, specialized cell fragment that triggers the clotting of blood so that damaged vessels stop bleeding Normally 150,000 to 300,000 platelets are found in one milliliter of blood, but platelet counts can become sharply depleted during HIV infection (See Immune Thrombocytopenic Purpura ) Another function of platelets is to collect antigen-antibody complexes in the blood Platelets coated with such complexes are eliminated in the spleen The source of platelets is megakaryocyte cells in the bone marrow
One of the three major blood cells, others being the red and white cells Platelets plug up breaks in the blood vessel walls and stimulate blood clot formation Platelets are the major defense against bleeding Also called thrombocytes
