#25: An Abundance of Spit
We all have saliva in our mouths, and we don’t make too much of it. But can you believe that our mouths produce approximately two liters of saliva per day? That is a huge number! There are many factors that can play into this, as there are certain causes of saliva to be secreted by the human body.
You may remember Pavlov and his dog. Whenever he brought a treat out for his dog, his dog would begin to salivate. It’s within that dog’s nature, just as it is with humans. You may find your mouth watering if you smell something delicious cooking or baking in the oven, for example. Also, when you’re eating, your body is constantly producing saliva which helps it breakdown that food in your digestive system.
