Quote by Ivan Pavlov
Edible substances evoke the secretion of thick, concentrated saliva. Why? The answer, obviously, is that this enables the mass of food to pass smoothly through the tube leading from the mouth into the stomach.
Summary
This quote suggests that when we consume edible substances, our body produces thick and concentrated saliva. The purpose of this saliva secretion is to aid in the digestion process by helping the food move easily through the esophagus and into the stomach. The thicker saliva assists in lubricating and breaking down the mass of food, allowing for a smoother passage into the digestive system.
