Label: "Vessel injury → Collagen exposed → vWF bridges → GpIb attaches" Step 2 - SHAPE CHANGE: Show platelets transforming from flat discs to round spheres with spiky pseudopods extending outward. Label: "Discoid → Spherical + Pseudopods" Step 3 - ACTIVATION: Show activated platelets releasing granules labeled ADP, Ca²⁺, and TXA₂ with small arrows showing recruitment of more platelets. Label: "Release: ADP, Calcium, TXA₂ → Recruit more platelets" Step 4 - AGGREGATION: Show multiple activated platelets clumping together, with GpIIb/IIIa receptors on their surface and fibrinogen molecules bridging them. Label: "GpIIb/IIIa expressed → Fibrinogen bridges → Platelet plug" Step 5 - STABILIZATION: Show the platelet plug reinforced with a fibrin mesh network from the coagulation cascade. Label: "Coagulation cascade → Fibrin mesh → Stable plug" Style: Clean medical illustration, white background, simple flat design, bright colors for each step (blue, orange, green, purple, red), clear bold labels, suitable for a presentation slide.
