Platelet Adhesion and Aggregation

Developed and produced for by Mechanisms in Medicine Inc. Animation description: Platelet adhesion and aggregation. In flowing blood, red cells predominate in the axial stream, while the biconvex disc-shaped platelets are marginated along the vessel wall where they are well-positioned to monitor the integrity of the endothelium. The normal endothelium provides a non-adhesive surface to circulating platelets. However, when vessel wall injury occurs, for example, by
