So what the parasympathetic system does is it basically decreases the rate of the heart and it decreases our respiration rate, basically the opposite of what the sympathetic nervous system did. Because we're not sweating as much, we don't have to worry about sweating as in this case. So our sweating basically drops at the same time because we just ate. 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.
