We have to digest our food and we have to absorb our food, the nutrients inside the small intestine. So what happens is the digestion rate basically increases. Our excretory system is working much more than before and we're no longer inhibiting, we're inducing our peristalis so that we can actually move that food along our small intestine. So the parasympathetic division of our autonomic nervous system is responsible for the rest and digest activities. This means it increases the flow of blood to our digestive organs and excretory system. So that means the blood vessels carrying blood to our digestive organs increases in size, they dilate, while our blood vessels that carry our blood to our skeletal tissue decreases in size.
