Detailed explanation-1: -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.
Detailed explanation-2: -A normal platelet count ranges from 150, 000 to 450, 000 platelets per microliter of blood. Having more than 450, 000 platelets is a condition called thrombocytosis; having less than 150, 000 is known as thrombocytopenia.
Detailed explanation-3: -Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.
