GlossaryPlatelet Activation

process where blood cells change shape to form clots

Platelet activation is a process where platelets, a type of blood cell, become stimulated and change shape to help form blood clots. This is crucial for stopping bleeding and initiating wound healing. When activated, platelets release chemicals that attract more platelets and other cells to the injury site, creating a plug to seal the wound.
