How do hormone responses occur so rapidly? When people are frightened/surprised, they can almost immediately feel a rush of adrenaline and heart rates rise, faces flush, etc. How do hormones reach appropriate organs so quickly? Why isn’t there more of a delay for the hormones to travel?

Too comment is the most accurate. But to help you understand why everything is so fast realize this: your body is only a couple feet long; your blood is traveling around 3mph.

Your heart is one of the hardest working muscles in your body for a reason. Your blood travels fast and your lymph travels nearly as fast(?)
