Document Summary

The main hormones (hemopoietic growth factors) that regulate the differentiation and proliferation of some specific progenitor cells of blood cells; and their effects. Blood clotting, the main steps of the intrinsic and extrinsic pathways; the info about the intravascular clotting is supposed to be the main focus for this question. Make sure to distinguish intravascular clotting from embolism. In the presence of ca2+, tf begins a sequence of reactions that activates clotting factor x: once clotting factor x is activated, it combines with factor v in the presence of. Intrinsic pathway: more complex than the extrinsic pathway, and occurs more slowly, usually requiring several minutes. Outside tissue damage is not needed: activators are either in direct contact with blood or contained within the blood. If endothelial cells become roughened or damaged, blood can come in contact with collagen fibers in the connective tissue around the endothelium of the blood vessel.
