What Two secretions that help to lubricate food?

* Saliva: Produced by the salivary glands in your mouth, saliva contains water, mucus, and enzymes that help break down food. The mucus in saliva acts as a lubricant, making it easier for food to slide down your esophagus.

* Mucus: This sticky substance is produced by cells lining the digestive tract, including the esophagus, stomach, and intestines. It coats the lining of these organs and helps to protect them from damage caused by food and digestive juices. Mucus also helps to lubricate food and aid in its passage through the digestive system.
