Clot the blood

Detailed explanation-1: -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.
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: -A blood clot is mass of blood that forms when platelets, proteins, and cells in the blood stick together. When you get hurt, your body forms a blood clot to stop the bleeding. After the bleeding stops and healing takes place, your body usually breaks down and removes the blood clot.
