Great Video!! i just needed to comment on the last part of the video that is the effect of Norepinephrine on the blood vessles to diliate them and not to constrict them :-D
@faddy1987wayne Correct me if i'm wrong but i think it actually does both: it constricts them through their action on the alpha 1 adrenergic receptors and it dilates them through the action on the beta 2 receptors (also responsible for the bronchodilation).
I think the vasoconstrive action is more pronounced though because of the greater affinity of norepinephrin for alpha 1
