Question
Chapter 18.4, Problem 20WDYL
Summary Introduction
To determine:
The difference between intrinsic and extrinsic pathway of blood clotting cascade.
Concept introduction:
Platelets, which are also called as thrombocytes are the membrane-bound cell fragments. They do not have a nucleus and are not considered as true cells. The main function of platelets is maintaining the hemostasis. It is a process by which bleeding was stopped by clotting of blood at the time of injury or cut. The initiation of blood clotting is a cascade of processes which occurs by two mechanisms: intrinsic and extrinsic pathway.
