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.
