Now, what exactly is the function of our platelet? Well, as the platelets actually move along our blood vessel, if some type of cut develops inside our blood vessel, these platelets essentially bind to that cut and they begin to aggregate. And in a matter of five minutes they essentially form a temporary patch. And they also create different types of chemicals. They release chemicals that ultimately call other cells into that location and that helps to patch up that cell that cut within our blood plasma. Now let's move on to a granular side.
