There are now clinical laboratory assays that assess hemostasis at different steps within the process.

Before discussing these components in more detail, it is important to realize that while we discuss them within this course separately for learning, they are very much interconnected in the body.
This flow diagram demonstrates the steps we will take to review the basic physiology of thrombosis. Use this flow chart as a guide to better understand the steps in the formation of a clot. Be aware that this chart does NOT include fibrinolysis or the natural coagulation inhibitors.
