Question

What are platelets? What is their function? Where are they present?

Answer 1

Platelets are tiny blood cells that help your body form clots to stopbleeding. If one of your blood vessels gets damaged, it sends out signals that are picked up by platelets. The platelets then rush to the site of damage and form a plug, or clot, to repair the damage.

Answer 2

Platelets, also called thrombocytes , are a component of blood whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot.
