Platelet aggregation is a core step in hemostasis—and when it’s dysregulated, it drives thrombosis. In this lecture from This is Why, Dr. Busti will break down platelet physiology in a clear, clinically relevant way so you can understand how platelets form a primary hemostatic plug, how a thrombus develops, and why this process matters in real patient care.

You’ll learn how to:

- How platelet adhesion starts (the role of von Willebrand factor (vWF) and GPIb)

- How platelet activation amplifies the response (ADP and thromboxane A2 / TXA2)

- How platelet aggregation occurs (GPIIb/IIIa binding fibrinogen)

- The key endogenous “brakes” that limit clot growth (nitric oxide and prostacyclin / PGI2)

- How clinicians think about platelet function testing and antiplatelet drugs in practice

The goal = make medical education easy and clinically relevant.
