Platelets are the cells that circulate within our blood and bind together when they recognize damaged blood vessels.
Platelets, or thrombocytes, are special blood cells that play a crucial role in blood clotting. They are essential for healing wounds and stopping bleeding. A normal platelet count is 150,000–450,000 platelets per microliter. A low platelet count can put you at risk for uncontrolled bleeding.
Platelets, or thrombocytes, are small, colorless cell fragments in our blood that form clots and stop or prevent bleeding. Platelets are made in our bone marrow, the sponge-like tissue inside our bones. Bone marrow contains stem cells that develop into red blood cells, white blood cells, and platelets.
The blood platelets are the smallest cells of the blood, averaging about 2 to 4 μm in diameter. Although much more numerous (150,000 to 400,000 per cubic mm) than the white cells, they occupy a much smaller fraction of the volume of the blood because of their relatively minute size.
Platelet disorders cause your platelet count to be too high or too low or your platelets not to work properly. Learn about the causes, symptoms, diagnosis, and treatments for platelet disorders.
Platelets are small discoid cells of 1-3 µm in diameter that circulate in the blood at a concentration of 1.4-4 x 10 8 /ml. The most well-known function of platelets is in hemostasis, where they are responsible for the formation of a vascular plug to prevent excessive blood loss following injury.
