"WebOct 23, 2024 · Platelets, also known as thrombocytes , are special blood cells with an important function. Platelets control blood clotting, which means they are critical 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. " - In the platelet release reaction quizlet
