I finally settled on platelet receptors and their role in blood clot formation. (I hope this follows through because the thought of changing my topic now is daunting)

Platelet Receptors and Signaling In the dynamics of Thrombus Formation
Information:
After reading these sources, I have figured out the basic process of blood clotting through alphaIIbbeta3 receptors. A receptor is activated by an
 activator (ligand) and the receptor's morphology changes from being bent (inactive) to straight up (active). In its active form, a fibrinogen molecule can bind to the receptors on the platelets. Throbin, a protein in the blood that helps with thrombus formation, causes the fibrinogen to form insoluble fibrin fibers. Theses fibers are the web-like structure of the clot and hold the platelets, cells and other clotting factors in place so the clot can form.

So far, I understand that when there is vascular injury, there is a chemical response, which triggers the integrins. What that chemical response and how that is triggered, I don't know yet.
Lets hope I can figure out the whole process!!
