Describe how platelets function
VashaNatasha [74]

Answer:

Platelets are tiny blood cells that help your body form clots to stop bleeding.

Explanation:

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.
