The major function of platelets (thrombocytes) in the human blood is to stop bleeding by initiating the process of blood clotting (hemostasis).

Platelets aggregate at the site of injury and form a plug, and they release factors that promote the coagulation cascade, leading to the formation of a fibrin clot.

Oxygen transport is primarily the function of red blood cells (erythrocytes) containing hemoglobin. Immunity is the function of white blood cells (leukocytes). Phagocytosis is a process carried out by certain white blood cells (like macrophages and neutrophils) to engulf and remove pathogens and debris.
