Why do we get a feeling in our gut/chest when experiencing very strong emotions?

For instance, when experiencing embarrassment, nerves... Love. Is this just an accident, a biproduct of our physiology; or is there an evolutionary reason for it?

The gut has more nerve endings than the brain, and a much higher concentration of neurotransmitters which help to regulate gut function. A flood of neurotransmitters such as serotonin and norepinephrine, caused by strong emotions and resulting in a temporary increase in gut neuronal activity, is likely the cause of these sensations.
