The total platelet count usually varies between 150,000 to 450,000 per microliter of blood and a single drop of blood has lakhs of blood platelets. Blood is a body’s fluid connective tissue, which circulates throughout the body under high pressure and helps maintain hemostasis. This Review provides an update of the latest developments in our understanding of platelet functions and populations in normal physiology and in haemorrhagic, thrombotic, and inflammatory ... Unchecked platelet activation and aggregation can culminate in the formation of unwanted clots and thrombosis within the vasculature. Understanding the intricate interplay of G-protein coupled receptors, calcium signaling, and cytoskeletal rearrangements is crucial. This knowledge will equip us to delve deeper into the mysteries of hemostasis and thrombosis, paving the way for future advancements in therapeutic interventions. Platelets are blood cells that form clots to stop bleeding. Learn about their origin, shape, granules, receptors, and role in hemostasis and immunity.
