Textbook Question
Chapter 18, Problem 4ILQ
View these animations (http://openstaxcollege.org/l/coagulation) to explore the intrinsic, extrinsic, and common pathways that are involved the process of coagulation. The coagulation cascade restores hemostasis by activating coagulation factors in the presence of an injury. How does the endothelium of the blood vessel walls prevent the blood from coagulating as it flows through the blood vessels?
