Platelets & Blood Clotting

The video explains the process of blood clotting, which prevents excessive bleeding and protects against pathogens. It starts with platelets forming a plug at the injury site, followed by fibrin strengthening the clot. This process results in a scab that protects the wound as it heals. The video emphasizes that clotting only occurs when necessary, preventing random clots in healthy vessels.
