Platelets A Tiny Cell Fragments
Abstract: Platelets are disc-shaped, anucleate cells that are approximately 2-3 μm in diameter. Their primary function is to control hemostasis, or blood clotting, but they also play important roles in angiogenesis (the formation of new blood vessels) and innate immunity (the body's first line of defence against infection). With a diameter of just 2-3 microns, platelets are tiny, disc-shaped cells that lack a nucleus. While their main responsibility is to ensure …
