(PLA-teh-leht) A formed element of blood that is active in blood clot formation.
Cytoplasmic fragment derived from megakaryocytes and involved in coagulation (thrombotic aggregation) and inflammation.
One of the three kinds of circulating blood cells. The normal platelet count is about 150,000 to 300,000. Platelets are responsible for creating the first part of the blood clot.
Also called thrombocytes, are small non-nucleated cells found in blood which play an important role in blood clotting in part by releasing seratonin at wound sites. They are formed by budding off of megakaryocytes found in bone marrow.
A substance necessary for blood clotting that is found in the blood.
Cells in the blood that are responsible for clotting.
A constituent of blood that help form clots to control bleeding.
small detached fragments of cytoplasm derived from megakaryocytes in the bone marrow; control clotting of blood and help repair wounds.
One of the components of blood that forms clots and prevents bleeding.
A substance in the blood which is necessary for blood clotting. Platelet transfusions are used in cancer patients to prevent or control bleeding when their platelet counts are low.
Type of blood cell. Helps the blood to clot. Platelet levels can drop during a course of chemotherapy.
a blood cell that helps to control bleeding by inducing clotting. Also called a thrombocyte.
Blood cell which helps to prevent bleeding.
a colorless disk-shaped body in blood that aids blood clotting
a small blood cell (protoplasmic disk) involved in coagulation and wound healing. HIV can lower a person's platelet count, causing severe bleeding. The normal platelet count is 200,000 to 300,000.
A small, round, or oval cell found in the blood, which is involved in blood-clotting.
A blood cell called a thrombocyte, important in the blood clotting process.
An irregular, disc-shaped element in the blood that assists in blood clotting. During normal blood clotting, the platelets clump together (aggregate). Although platelets are often classed as blood cells, they are actually fragments of large bone marrow cells called megakaryocytes.
A type of blood cell that helps prevent bleeding by causing blood clots to form. Also called a thrombocyte.
One of three kinds of formed elements found in blood that aids in the clotting of the blood.
Type of cell found in the blood that assists with clotting.
smallest and most fragile of the blood cells; primary function is associated with the process of blood clotting.
an irregularly shaped disk-like fragment of a larger cell that functions in clotting
One of the elements found in circulating blood. A platelet has a circular or disk-like shape is small; hence the term platelet. Platelets aid in blood coagulation and clot retraction.
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.
A component of blood that contributes to coagulation
a type of blood cell that helps the blood to clot. Chemotherapy can lower platelet count.
A type of blood cell fragment that helps prevent bleeding by helping to form blood clots. Also called a thrombocyte.
A component of the blood important in clotting. Inadequate amounts of platelets will lead to bleeding and bruising easily. (Read about " Bleeding Disorders")
Blood cells that make the blood clot.

a type of blood cell that helps the blood to clot. The normal range for platelets is between 150,000 - 500,000/mm 3 . An increased risk of serious bleeding occurs when platelets drop below 50,000/mm 3 .
A platelet is a disk-shaped structure present in the blood; they have several functions, all relating to stopping bleeding.
Type of blood cell responsible for helping the blood to clot. Also known as thrombocyte.
rregularly shaped cell fragments that assist in blood clotting. During normal blood clotting platelets aggregate (group together) to prevent hemorrhage.
A small cell in the blood which helps it to form clots.
A small blood cell needed for normal blood clotting.
A component of the blood responsible for the formation of clots in response to injury.
The smallest cells in the blood, essential for blood clotting.
a round or oval disk found in the blood, important in blood coagulation.
Cell fragment in blood which is involved in clotting
Small cells in the body that are responsible for clotting
A cell-like particle in the blood that plays an important role in blood clotting. Platelets are activated when an injury causes a blood vessel to break. They change shape from round to spiny, "sticking" to the broken vessel wall and to each other to begin the clotting process. In addition to physically plugging breaks in blood vessel walls, platelets also release chemicals that promote clotting.
Platelets are cells in the blood that control bleeding by plugging the broken blood vessel and helping the blood to clot.
A thrombocyte, the smallest of the formed components of blood, associated with blood clotting.
Platelets or thrombocytes are the cell fragments circulating in the blood that are involved in the cellular mechanisms of primary hemostasis leading to the formation of blood clots. Dysfunction or low levels of platelets predisposes to bleeding, while high levels, although usually asymptomatic, may increase the risk of thrombosis.
