A Level Biology Revision "Blood Clotting and Inflammation"

????

In this video, we look at blood clotting and inflammation. First we explore the process that takes place during blood clotting, including the roles of platelets and the clotting factor thromboplastin. We then look at what happens during inflammation, in particular the roles of mast cells, histamine and cytokines.
