In humans the process of digestion begins in the mouth where food is chewed into small pieces by the teeth. The saliva helps by moving pieces these pieces around. These pieces are covered by bland, or spit. The saliva makes the food slippery so it's easier to blank.

The saliva makes the food slippery so it's easier to SWALLOW.

Explanation:

Digestion of food begins from the mouth. When the food is chewed, it mixes with the saliva from the salivary gland and this makes the food slippery and easier to swallow. Once it is swallow it moved to pharynx to the oesophagus and down to the stomach where the stomach acid act on it. From there enzymes from the pancreases act on it to break it down and it is moved down to the small intestine where it is absorbed as nutrients and the undigested one move to the large intestine and form faeces.
