During hemostasis, which process occurs first?

Hemostasis is a process which would cause for bleeding to halt and is the first step in healing wounds. During hemostasis, the process that happens first would be vascular spasm. The damaged vessels are constricted  which would result to reducing the amount of the blood flowing in the area thus limiting blood loss.  This action is stimulated by factors like direct injury to a smooth muscle. This would allow chemicals to be released by the platelets and the endothelial cells. This response would be more effective as the damage is being increased. Also, it occurs more effectively in areas where there are smaller blood vessels.
