During a stressful situation, hormones are sent out to _________ your heart rate, and __________ blood vessels, which is known as the ___________ response. | increase, dilate, “fight or flight” |
Parasympathetic Division | responsible for promoting normal digestion, elimination of wastes, and conserving body energy "rest and digest" |
Why is it good to rest after eating? | So the parasympathetic division can go to work digesting - if a person is stressed physically, the sympathetic division takes over and causes blood to flow to the skeletal muscles instead of the digestive organs |
