What happens to saliva when you swallow it?

When you swallow saliva, it travels down the esophagus and into the stomach. Saliva aids in digestion by moistening food and containing enzymes that begin the breakdown of carbohydrates. Once in the stomach, saliva is mixed with gastric juices, contributing to the overall digestive process. Additionally, swallowing saliva helps maintain oral health by clearing bacteria and debris from the mouth.
