Platelets are vital in blood clotting, with a normal concentration of 150,000-400,000 per microliter of blood. They lack a nucleus, are disc-shaped, and play a crucial role in preventing uncontrolled bleeding.
Platelets are cell fragments produced from megakaryocytes in the bone marrow. They play a crucial role in blood clotting, with a normal concentration of 150,000-400,000 per microliter of blood.
Maintenance of this platelet count is essential as it helps prevent uncontrolled bleeding. Platelets lack a nucleus, are disc-shaped, and contain small vesicles.
Function: Platelets aid in forming clots by activating fibrinogen into fibrin, creating a mesh for clot formation, and stopping excess blood loss by sealing blood vessel tears.
